基于ANSYS的岩体边坡稳定性分析
首发时间:2009-04-07
摘要:应用ANSYS软件对某一高速公路岩体边坡开挖和加固进行有限元模拟计算分析,讨论分析了在边坡开挖完成时和加固处理后降雨入渗影响下该边坡的应力和位移分布规律,进而判断其稳定性。分析表明,该边坡拉应力区范围和拉应力数值均较小,可以满足稳定性要求;连续降雨对边坡稳定不利,需做好排水和隔水措施。

Stability Analysis of Rock Slope by ANSYS
Abstract:By use of the ANSYS, the finite element simulation and analysis is carried out for the excavation and reinforcement of rock slope of a highway. The distribution law of stress and displacement of the rock slope is analyzed and studied under excavation case and rainfall case, and the effect of rainfall on stability of rock slope is studied. Then the stability of rock slope is estimated. It is shown that the domain and numerical value of tensile stress of the rock slope are small, and the rock slope is stable under current condition. In addition, the continuous rainfall will bring obvious disadvantage on the stability of rock slope, and the measure of drainage and water insulation must be got down with.
