Testing and Modelling of Saturated Interfaces Under Cyclic Loading

研究界面相对运动对结构和基础动力响应的影响。它将提供一个新的和改进的机制，在动力土-结构相互作用的荷载传递受粗糙度和流体压力的影响。预计研究结果将有助于改善各种岩土工程问题的设计。将开发一个新的试验箱来模拟饱和砂-混凝土界面的行为。将进行一系列全面的实验室测试，并用于基于扰动状态概念和分层塑性模型的本构模型的开发。

The research is aimed to delineate the effect of relative motions at interface on dynamic response of structures and foundations. It will provide a new and improved understanding of the mechanism of load transfer in dynamic soil-structure interaction as affected by roughness and fluid pressures. It is anticipated the outcome will lead to improved designs of a wide range of geotechnical problems. A new test box will be developed to simulate behavior of saturated sand-concrete interfaces. A comprehensive series of laboratory tests will be performed and used for the development of a constitutive model based on the disturbed state concept and hierarchical plasticity models.
