9410482 Wathugala A general numerical procedure based on the strain path method, mixture theory and non-linear finite element method will be developed that will simulate pile driving, subsequent consolidaiton and pile load tests. This numerical method will be verified by simulating laboratory tests. An instrumented pile segment model which can continuously measure and record shear transfer, pore pressure and total radial pressure will be fabricated and tested. Four clay samples with different overconsolidation rations, confining pressures and drainage conditions will be studied in these tests. ***

9410482瓦图加拉将开发一个基于应变路径法、混合理论和非线性有限元方法的通用数值程序，用于模拟打桩、随后的固结和桩的载荷试验。该数值方法将通过模拟实验室试验进行验证。建立了能够连续测量和记录剪切传递、孔压和总径向压力的仪表式桩段模型，并进行了试验。试验将对四种不同超固结比、围压和排水条件的粘土样品进行研究。***
