APPLYING CENTRIFUGE TESTS FOR STUDYING SOIL RESPONSES TO BREAKING WAVES IN SWASH ZONES

Modeling Breaking Waves and Studying Amplitude Dependent Behavior

This project implements a method, presented by Longuet-Higgins and Cokelet, for modeling the breaking of ocean waves. Five waves are generated, with the same shaped profile but different amplitudes. Their behavior over time is compared, and it is seen that higher amplitude waves break faster and with a sharper point. Additionally, a variable S is calculated to measure the surfability of these w...

Axially - Loaded Centrifuge Pile Tests

Numerical simulation of centrifuge tests on homogeneous and heterogeneous soil models

Soil liquefaction is a major cause of seismic damage in cohessionless soil during earthquakes. From past numerical and experimental research it has been observed that more excess pore water pressure (EPWP) is generated during earthquakes in a heterogeneous soil deposit than in the corresponding homogeneous soil with relative density equal to the average relative density of the heterogeneous soi...

Liquefaction of Heterogeneous Soil: Centrifuge Study

A series of centrifuge liquefaction tests have been conducted at C-CORE’s geotechnical centrifuge facility: two on variable soil and one on uniform soil deposits. A single storied frame structure resting on two strip footings was also placed on that soil deposit. Experimental results such as accelerations, excess pore water pressures (EPWP) and settlements were monitored throughout the tests. R...
