FLAC^(3D)在地震边坡稳定性分析中的应用

The Application of FLAC^(3D) to the Analysis of Slope Stability in Earthquake

介绍了FLAC^(3D)基本原理和动力分析的特点;通过对某土质边坡的地震荷栽动力分析,讨论了利用FLAC^(3D)进行边坡地震动力分析时如何设置边界条件、地质体阻尼的选取、地震波的时程转化和输入.在此基础上,依据边坡地震荷栽作用下的边坡位移变形和塑性区域的贯通情况对边坡稳定性进行了分析.

The stability analysis of slope with FLAC^3D in earthquake is introduced in this paper. The issues of basic theroy of dynamic analysis with FLAC^3D,boundary conditions, dynamic wave transfrom and load, and damping for geological body are discussed .The stability of slope in earthquake is estimated based on the displacement and plastic distortion area transfixion with FLAC^3D.
