摘要
随着高等级公路向山区的纵深发展,许多地方都遇到了性质介于岩质边坡和土质边坡之间的过渡型边坡—类土质边坡,及其引起的工程地质问题,为了进一步提高仿真设计的准确性和科学性,本文以目前在土木工程中广泛采用的有限单元法为理论基础,采用ABAQUS有限元软件,引入Mohr-Coulomb塑性模型,采用强度折减法,对类土质路堑高边坡的典型失稳机制进行数值模拟研究。
With the development of the highway to the mountains,many places have experienced class soil slope,the nature of it between the rock slope and the soil slope.It has caused a lot of engineering geological problems.For improveing the accuracy of scientific simulation design,the finite element method as an widely used in civil engineering theoretical basis is used in this article.Using ABAQUS finite element software,introducing Mohr-Coulomb plasticity model,using strength reduction,to discuss numerical simulation of instability mechanisms in similar soil high-slope.
