ANSYS在排土场动力时程分析中的应用
|
摘要
简要介绍运用ANSYS进行动力时程分析的基本原理,结合某石灰石矿排土场边坡稳定性问题,对排土场进行了简化为二维平面问题的地震时程分析。得出排土场边坡在地震作用下不同位置质点的位移和加速度响应特征,对边坡工程的动力分析具有参考意义。
The theory of transient dynamic analysis with ANSYS is described briefly.A seismic transient dynamic analysis,which is simplified to a 2D model,is made for the stability of dump slope of a limestone mine.As a result,the characteristic of displacement and acceleration response of different points in the dump slide are defined,which can be reference to the slope engineering dynamic analysis.
