Electronic Computer Program For The Solution Of Slope Stability By The Wedge Method Of Analysis., James O. Boardman

Civil Engineering ETDs

Earth embankments and the foundation upon which they rest are subject to abear stresses induced by their own weight. It the embankment serves as a water retention structure, additional shear stresses are developed by seepage forces originating from pore pressure, from the reservoir pool and from rainfall. In certain regions, earthquake forces must also be added to these gravity and water forces.

Prior to the turn or the century and tor thirty some years after, earth dam side slopes were selected on the basis of past experience in lieu of a theoretical analysis. Justin, a noted authority on earth dam …

Stage-Fall-Discharge Relations For Flood Flows Over Highway Embankments, Gaylord V. Skogerboe, M. Leon Hyatt, Lloyd H. Austin

Reports

At Utah State University, considerable effort has been devoted to the analysis of submerged flow at open channel constrictions. A method of analyzing submerged flow was first developed for a trapezoidal flume by Hyatt (1965). Later studies verified the method of analysis for a rectangular flume (Skogerboe, Walker, and Robinson, 1965) and Parshall flumes (Skogerboe, Hyatt, England, and Johnson, 1965). Because of the previous findings, it was felt this method of analyzing submerged flow could be applied to highway embankments.

A highway embankment is a form of broad-crested weir when overtopped by flood waters. Being a weir, the flood discharge …

Impact Of I 75 On The Local Economy Between Walton And Georgetown, Robert C. Deen

Kentucky Transportation Center Research Report

In 1956 the National Interstate and Defense Highway System was approved by Congress. It was immediately apparent that the diversion of traffic to such a system could result in immediate and lasting significant changes in the traffic flow patterns on the older highways, and this probably would have an immediate effect upon the businesses located along these older highways. In the bill authorizing the Interstate Highway System provision was made for studies of the economic effects of the new system upon local economies. The study reported herein is a part of a long-range investigation of the various aspects of economic …

Piggery Septic System, N E. Macintyre

Journal of the Department of Agriculture, Western Australia, Series 4

ONE of the problems of intensive houses for pigs is the disposal of the dung and urine.

If proper arrangements are not made to remove this, it soon accumulates in an offensive pile at one end of the piggery, making an excellent breeding ground for flies.

Termites Or White Ants, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

TERMITES are commonly but erroneously called "white ants."

Actually they are more nearly related to cockroaches than to ants, but their general appearance and subterranean habits have given strong support to the popular designation.

They may be divided into two major groups from an economic point of view, viz., wood-dwelling and earth-dwelling termites.

Composite Pavement Design, James H. Havens

Kentucky Transportation Center Research Report

There is an aura of superiority attached to the work "composite"--that is to say, the composite of anything is expected to be superior to its distinct elements of parts. It will suffice here to define a composite pavement as being compounded of "rigid" and "flexible" parts or layers. In reality, we mean layers of portland cement concrete and bituminous concrete--each of which is admirably sufficient in itself or may be so down-graded to satisfy lesser desires. Even so, we seem always to be discontent with the status quo. We are all somewhat opinionated on matters of pavement design and …

The Effect Of Epoxy Resin In Stone And Slag Concrete, James Chun-Min Chou

Masters Theses

"In concrete construction, the weight of the structure represents a large portion of the total load carried; thus, there is considerable advantage in reducing the weight of the concrete. To obtain this result, there are at least three approaches (1). The first method of producing lightweight concrete is by means of substituting a porous lightweight aggregate of low specific gravity for the ordinary aggregate. The second method relies on introducing large voids within the concrete or mortar mass; this is known as aerated, cellular or gas concrete. The third method is simply to omit the fine aggregate from the mix …

Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin

Reports

Submerged flow exists for any given structure when a change in flow depth downstream from the structure causes a change in flow depth upstream from the structure for any given constant value of discharge. The two flow depths, normally measured when submerged flow exists, consist of a depth upstream from the structure, which is used also for free flow conditions, and a depth of flow located any place downstream from the structure. The initial studies in which the submerged flow analysis was developed were made on flat-bottomed flumes (Hyatt, 1965; and Skogerboe, Walker, and Robinson, 1965). Later studies verified the …

Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe

Reports

Because the accurate measurement of water plays such an important part in water management, such structures as weirs, orifices, calibrated gates f and flumes have been developed. These structures provide the means for reasonable measurement of the smaller flows (1: .. 100 cfs), but for the large flows (100-3,000 cfs) the current meter, large Parshall flume, and various other flumes are commonly used. Where a permanent structure is required, the most widely accepted and utilized method for measurement of large flows is probably the Parshall flume. The purpose of this report has been to collect the existing flow data for …

Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen

Reports

The general hydrodynamic equations for a spatially varied unsteady flow in a prismatic open channel having an arbitrary cross-sectional shape can be derived from the equations of continuity and momentum. The assumptions based on the general concept of hydrodynamics and the theory of shallow water is introduced. The mathematical models in the surface irrigation can be formulated by these equations of motion with the appropriate initial and boundary conditions prescribed at the singularity point (the origin in the x, t-plane) and at x = 0. Therefore, the flow in the surface irrigation must be described by solving the boundary-value problem …

A Numerical Method For The Solution Of Cylindrical Shell Structures, Chen-Jow Hsiao

Masters Theses

"Many studies and analyses of shell structures to date have been either so complex and laborious as to preclude their application in practical design problems or so approximate, because of basic assumptions, as to limit their scope of application. Hence, a method of shell analysis which is convenient to use, reasonable in its results and general in its application is really needed. It is the purpose of this study to supply such a method of analysis.

In this investigation it is proposed to replace the shell structure which has an infinite number of degrees of indeterminancy with an analogous framework …

A Numerical Solution For Beam-Columns On Non-Linear Foundations, Wendelin H. Mueller Iii

Masters Theses

"A program for Matlock's recursive method, a numerical method which will analyze beams and columns with linearly varying spring supports, was modified to enable the solution of such members supported by non-linear springs. This modification was accomplished by an iterative technique. The final result of this paper is a computer program which can be used to solve beams or columns with non-linear spring supports, giving as output the deflection, slope, moment, shear, net load and curvature of the structure at uniformly spaced locations"--Abstract, page ii.

Checking Rigid-Framed Structures By Extended Moment-Area Equations, Lucky Li-Chi Chow

Masters Theses

"Using the known moments obtained from the moment distribution solution, the extended moment-area equations are used to check whether or not delta x, delta y, delta theta are truly zero, or are any other quantity they are supposed to be. In order to get a reasonably correct answer, a solution must meet both the elastic checks and the static checks for their equilibrium and compatibility functions. Using the extended moment-area equations, the magnitudes of the slopes and deflections at all of the joints in framed structures can be found easily"--Abstract, page ii.

Some Effects Of Selected Biodegradable Detergents On The Aeration Of Water And Activated Sludge, Donald Ernest Modesitt

Masters Theses

"The purpose of this study was to determine what effects the presence of selected biodegradable detergents have on the aeration of water and the activated sludge process for aerobic wastewater treatment. The detergents studied were LAS #1, Alfol, and Nalkylene. It was of particular interest to determine if these detergents decreased the oxygen absorptive capacities of water and wastewater. If detrimental effects were produced by the detergents it was then desired to determine if these effects were serious enough to create problems with aerobic wastewater treatment and aeration in receiving bodies of water.

Modification Of The Hydraulic Jump By Submerged Jets, Edward Leon Tharp

Masters Theses

"Tests were performed in order to determine the effect of submerged jets injecting water into the base of the hydraulic jump. The jump was studied in terms of the following properties: specific energy of the flow leaving the hydraulic jump, length of the hydraulic jump, tailwater depth, and wave formation properties. These properties for the hydraulic jump with submerged jets were compared to the natural hydraulic jump.

Results of the tests indicate that: submerged jets at any angle tested tend to decrease the specific energy of the water leaving the jump and are more effective than the impulse-momentum principle indicates, …

Masters Theses

"A method for analyzing single and multi-span gabled frames using analysis charts is presented. This method requires considerably fewer computations than methods previously used (such as the moment distribution and slope-deflection methods). Analysis charts are presented for single gabled frames having fixed or pinned ends at ground level, and charts are also presented which can be used to efficiently analyze multi-gabled frames.

The data for the analysis charts were obtained using matrix techniques in conjunction with the digital computer. These techniques are described"--Abstract, page ii.

Some Effects Of Sodium Pentachlorophenol On Activated Sludge And Minnows., James Albert Heidman
