摘要
基于动力响应时程分析原理,结合西部某含软弱夹层风化岩质边坡工程实例,借助AD INA有限元程序采用以下方法分析边坡地震动力响应:首先进行静力有限元分析,确立初始应力场,然后输入地震波,研究位移、应力、和加速度的动力响应结果。研究表明:软夹层对边坡动力特性影响显著,计算取得了比较满意的结果。
Based on the principle of dynamical response time-dependent analysis, the dynamic response and stability of the weathering rock slope which contains soft soil layer were analyzed with ADINA program in the following way. Firstly, the static finite element analysis was made to determine the initial stress field. Then, the slope dynamic response was analyzed and the stress, displacement, and acceleration were studied. Dynamic response results of slope in the seismic action are achieved by means of timedependent analysis ,which can be applied to reflect the dynamic characteristics of slope.
