根据摩尔—库仑理论推导出判断土体某点稳定的充要条件,提出基于该条件利用有限元进行土体稳定性分析的数值方法,探索了具体的建模—求解—后处理技术,并基于ANSYS参数化模型对锚杆加固范围和隧道埋深进行讨论,实践和计算表明,本方法是土体稳定性分析准确高效的一种新手段。%According to the Mohr Coulomb theory deduced the necessary conditions for judging soil stability of some sufficient,based on the conditions put forward the numerical method for stability analysis on soil body using finite element,probed the concrete modeling-solution-post processing technique,and discussed the bolt reinforcement scope and buried depth of tunnel based on ANSYS parameter model.Practice and calculation showed that,this method was an accurate and efficient new method for soil body stability analysis.
