砂砾石垫层在水平动力作用下软化响应模型
Response Model of Gravel Cushion Softening under Action of Horizontal Dynamic
摘要
Abstract
Based on experimental study on response of the gravel cushion under horizontal vibration loads, this article has pointed out the response characteristics, which are caused by the movement and structure softening of the self-organization and particles in gravel cushion, including local effects, shear resistance and time effect, etc. We have simulated the response process of the gravel cushion softening by using Poisson process, and then established the prediction model. This study has laid the foundation for research on status of gravel cushion after a number of multi-earthquakes, and research on isolaed earthquake of the gravel cushion.关键词
