Rainfall-induced landslides are one of the most frequent hazards on slanted terrains. They lead to considerable economic losses and fatalities worldwide. Intense storms with high-intensity and long-duration rainfall have high potential to trigger rapidly moving soil masses due to changes in pore water pressure and seepage forces. Nevertheless, regardless of the intensity-duration of the rainfall, shallow landslides are influenced by antecedent soil moisture conditions. To the present day, no system exists that dynamically interrelates these two factors.
This work establishes a relationship between antecedent soil moisture and rainfall expressed in the form of a Shallow Landslide Index (SLI) at 1km ...

Motor vehicle crashes are one of the leading causes of death in the United States. The most recent data available show that in 2006 there were almost 6 million police-reported motor vehicle crashes in the United States where a total of 42,642 people were killed and an additional 2.6 million were injured. The majority of these motor vehicle crashes occurred at intersections or within the intersection influence areas. Traffic conflicts occur at intersections due to traffic streams moving in different directions interfering with each other, and as a result they become areas with high potential for traffic crashes ...

Electrokinetics And Vacuum Combined Dewatering Of Oil Sand Tailings, Rui Zhang
Electronic Thesis and Dissertation Repository
One of the challenges faced by the oil sand industry is the dewatering of mature fine oil sands tailings (MFT) due to the low permeability. Vacuum pressure or electrokinetic (EK) dewatering is effective to meet this objective. This research was focused on the experimental study and analytical modelling to explore the influence of combined vacuum and EK treatment on MFT. In this study, systematical experiments on MFT recovered from the northern Alberta were carried out. At first, the characterization and EK cell tests were conducted to measure the basic properties and the coefficient of electroosmotic permeability (ke) of MFT. Secondly ...

Rowan University
Determination Of Non-Nuclear Alternative To The Nuclear Density Gauge Through Laboratory And Field Testing, Janine Abyad
Theses and Dissertations
Pavement performance is dependent on the compaction quality of unbound subgrade and base/subbase layers beneath flexible pavements. Pavement distresses can be linked to compaction defects within these layers. In current practice, the New Jersey Department of Transportation (NJDOT) utilizes the nuclear density gauge (NDG) for evaluating compaction quality based on minimum density requirements, typically 95% of the Proctor maximum dry density (MDD). However, there are concerns with using the NDG. The goal of this study was to replace the NDG with non-nuclear alternative method(s) as acceptance tools during field compaction. To achieve this, a laboratory procedure for compacting ...

Kinematic Behavior Of Sheared Sand With Emphasis On Particle To Particle Interaction Using Computed Tomography, Maha Fawaz Jarrar
Masters Theses
Granular materials are a three-phase mixture of solid, liquid, and gas that exhibit complex engineering properties. They have a heterogeneous composition in nature and consist of many discrete particles with complex interactions. Granular materials are commonly used in many civil engineering construction projects, therefore, a better understanding of behavior of granular materials may result in safe and economical design. This thesis is a compilation of two related topics. A 3D systematic experimental study that investigates the influence of particle morphology, confining pressure, and specimen density on the failure mode of sheared sand is presented. Three uniform sand specimens with different ...

Validation Of An Internal Camera Based Volume Determination System For Triaxial Testing, Leah D. Miramontes
Civil Engineering Undergraduate Honors Theses
Accurate strain and volume measurements are critical to phase relationships and strength determination for saturated and unsaturated soils. In recent years, laboratory-based photographic techniques of monitoring soil specimens have become more common. These techniques have been used to reconstruct 3D models and to determine strain and volumetric changes of triaxial specimens. A new technique that utilized digital photographs of the soil specimen, captured from within a triaxial testing cell, was utilized. Photographs were processed using photogrammetry software to reconstruct 3D models of the soil specimens. By placing camera equipment within the cell, the technique eliminated the need to account for ...

Numerical Modelling Of Wind Turbine Foundations Subjected To Combined Loading, Venkatesh Madhukar Deshpande
Electronic Thesis and Dissertation Repository
With the growing wind industry in Canada, it has become important to optimize wind turbine foundation design. Wind turbine foundations are subjected to combinations of vertical, horizontal and moment loads due to vertical self-weight of the structure and soil surcharge. Additionally, there are significant lateral loads and overturning moments attributed to varying wind forces acting at considerable tower heights above the ground level. In this thesis, the undrained bearing capacity response of circular & octagonal foundations subjected to combined loading is calculated using finite element analyses. Previous works have mostly focused on circular foundations. An octagonal foundation of the style typically ...

Full-Scale Shake Table Cyclic Simple Shear Testing Of Liquefiable Soil, Jasper Stanford Jacobs
Master's Theses and Project Reports
This research consists of full-scale shake table tests to investigate liquefaction of sandy soils. Consideration of the potential and consequences of liquefaction is critical to the performance of any structure built in locations of high seismicity underlain by saturated granular materials as it is the leading cause of damage associated with ground failure. In certain cases the financial losses associated with liquefaction can significantly impact the financial future of an entire region.
Most liquefaction triggering studies are performed in the field where liquefaction has been previously observed, or in tabletop laboratory testing. The study detailed herein is a controlled laboratory ...

Underwater Explosion Energy Dissipation Near Waterborne Infrastructure, Paul R. Smith
Theses and Dissertations--Civil Engineering
Underwater explosions pose a significant threat to waterborne infrastructure though destructive pressure waves that can travel significant distances through the water. However, the use of bubble screens can attenuate the peak pressure and energy flux created by explosions to safe levels. This study investigates the prediction of pressure wave characteristics based on accumulated data, the damage potential of underwater explosions based on applied loads and effective material strength, and the bubble screen parameters required to prevent damage. The results were compiled to form a procedure for the design and implementation of a bubble screen the protection of waterborne infrastructure.
Pore Pressure Measurement Instrumentation Response To Blasting,

Pore Pressure Measurement Instrumentation Response To Blasting, Kylie M. Larson-Robl
Theses and Dissertations--Mining Engineering
Coal mine impoundment failures have been well documented to occur due to an increase in excess pore pressure from sustained monotonic loads. Very few failures have ever occurred from dynamic loading events, such as earthquakes, and research has been done regarding the stability of these impoundment structures under such natural seismic loading events. To date no failures or damage have been reported from dynamic loading events caused by near-by production blasting, however little research has been done considering these conditions. Taking into account that current environmental restrictions oblige to increase the capacity of coal impoundments, thus increasing the hazard of ...
