软土地基堆土边坡数值模拟的建模过程分析

Analysis of Modeling Process for Numerical Simulation of Earth Slope on Soft Soil Foundation

摘要:

软土地基边坡分析除满足静力平衡条件外,应重点关注由于变形导致的坡脚局部隆起变形,利用有限元计算软件可对边坡进行整体变形计算；本文针对岩土工程设计中运用广泛的迈达斯GTS NX软件,在摩尔-库伦本构模型基础上,通过对各项参数取值来源进行分析,并通过构建典型模型对建模过程进行演示,给出同类工程数值模拟的合理化建议。

Abstract:

Midas GTS NX software widely used in the geotechnical design is applied. On the basis of Moore-cullen constitutive model, through the analysis on value source of each parameter and the establishment of the typical model to demonstrate the modeling process, the rationalization proposal is put forward for the numerical simulation of the similar projects.
