Development Of Dynamic Testing Machine For Laboratory Modeling Of The Rock Fracturing Phenomenon, Mohammad Ali Moghaddass Zadeh Kermani

Theses

The purpose of this thesis is to develop a dynamic testing machine for laboratory modeling of the rock fracturing phenomenon. Bearing stratum fracturing is a construction difficulty which occurs when end-bearing piles are driven to weak rock or weathered sound rock. It is a pile group effect and can result in significantly less pile carrying capacity than the final driving resistance would normally indicate.

A linear scaling factor was derived to establish similitude between the laboratory apparatus and field conditions. This scaling factor is approximate and was used for overall sizing of the apparatus and its components. A more exact …

Hydraulic Rams For Rural Water Supply Schemes In Selected Areas In Tanzania, T Mbwette

Tanzania Journal of Engineering and Technology (TJET)

This paper presents one of the many efforts made by the Faculty of Engineering and the Institute of Production Innovation of the University of Dar es Salaam towards the realization of the International Water Supply and Sanitation Decade. Special reference is made to the use of hydraulic rams along with some simple water treatment methods. Besides the account of theoretical and practical work done to-date in the field of water supply, a further evaluation of the theoretical model presented is recommended so as to enable a judgement of the present hydraulic ram designs to be done. Tests on a typical …

A Review And Analysis Of Pile Design, David L. Allen

Kentucky Transportation Center Research Report

A review of lateral load design of piles is presented. It appears many different methods and allowable lateral loads are permitted by the states. One particular method is discussed in detail, and from that method two charts are presented that relate pile deflection to lateral load. Recommendations are given on design criteria for lateral loads.

A review of allowable axial stresses is also presented. The results of a brief finite element analysis of pile tip settlement versus load for various conditions are also presented. These results are compared to data obtained from the literature. Recommendations on maximum allowable axial stress …

Evaluation Of Durable Crosswalk And Stopbar Marking Materials (Interim Report), Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

The objective of this study is to find the most cost-effective durable marking material to provide long-lasting stop bars and crossbars. Three materials were tested: 1) 3M Stamark tape, 2) Prismo preformed tape, and 3) extruded thermoplastic. The evaluation concerned the durability, reflectivity, and appearance of the materials. Test installations have been in place for about 18 months, and this interim report summarizes findings for that period. The evaluation will continue for another 18 months, and recommendations will be presented in a final report.

Based on current evaluations, the extruded thermoplastic material would be considered the most cost-effective material for …

Evaluation Of Durable Lane Delineation Materials (Interim Report), Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

The objective of the study is to evaluate the cost-effectiveness of available marking materials by means of field tests and to develop a policy for material selection of lane delineation based on these tests. Materials tested included: 100 percent solid epoxy paint, polyester paint, extruded thermoplastic, 3M Stamark tape, 3M Bisymmetric tape, EPOFLEX, solvent epoxy paint, and chlorinated rubber paint. Most test installations have been in place for over two years, and this interim report summarizes findings for that period. The evaluation will continue for another 18 months with recommendations presented in a final report.

Based on current data, expanded …

Pavement Management In Kentucky, Gary W. Sharpe, Robert C. Deen, Herbert F. Southgate, Rolands L. Rizenbergs, James L. Burchett

Kentucky Transportation Center Research Report

The principal objective of this paper is to summarize current pavement management activities in Kentucky. Early pavement management activities generally were decentralized (involving a number of transportation functions such as planning, design, construction, maintenance, and research) and involved long-term monitoring for skid resistance and ride quality (roughness).

Current pavement management activities may be categorized by evaluation, project selection, and development of recommendations for pavement rehabilitation strategies. Pavement evaluation activities at the statewide system level typically involve assessments of ride quality (ridesbility index) and estimated pavement serviceability, skid resistance, visual condition ratings, and the accumulation of traffic volumes and pavement fatigue. …

Application Of Combined Jointed Media And Discrete Slip Plane Characteristics To Subsidence Predictions, David W. Basinger

Theses and Dissertations

This thesis presents an application of a numerical formulation incorporating the effects of joints, cracks, and fractures to a soil subsidence predictions problem, and the extension of that formulation to combined discrete slip planes and jointed media continua formulations. The results obtained are compared to each other and to a physical centrifuge simulation performed previously on the same problem.
