| 摘 要： | 针对人们对加筋土挡土墙长期蠕变后地震动力响应特性认识还很模糊的问题,利用ABAQUS软件,以一高8m高黏性土填土的加筋土挡土墙为例,同时考虑土体与筋材蠕变效应,对其经历5a蠕变后再遭遇地震作用的整个过程进行了有限元模拟分析,并重点研究了不同类型地震波的影响,其中,土体采用实用弹塑-黏塑性模型,筋材采用土工合成材料循环受...

| Abstract: | In order to study the seismic behavior of geosynthetic-reinforced soil walls after long-term creep,the process of an 8 m-high cohesive back-filled geosynthetic-reinforced soil retaining wall subjected to earthquakes after five years of creep was analyzed with consideration of creep effects of the soil and the reinforcement material simultaneously using the finite element software ABAQUS.The effects of different types of earthquake waves were emphatically studied.In the analysis,the soil and the reinforcemen... |
