DILATANCY BEHAVIOR OF SOIL-STRUCTURE INTERFACES AND ITS SIMULATION
-
摘要: 通过对土与结构物接触面力学特性的分析,总结出4种基本的接触面应力-应变曲线形式。提出一个新的剪胀方程及其对应的剪胀函数,对接触面的剪胀特性进行描述。与一般土的剪胀方程相比,新剪胀方程显得更为合理。Abstract: According to the deformation mechanism of soil_structure interface,four types of stress_strain curves are summarized.A dilatancy equation and its corresponding dilatancy function are established to simulate the dilatancy behavior of soil_structure interface.It is shown that the new dilatancy function can describe the dilatancy behavior well.
