沥青拌合站土质边坡变形特征及稳定性分析

Deformation characteristics and stability analysis of soil slope in asphalt mixing station

结合老河口公路局沥青拌合站土质边坡周边工程地质条件分析了边坡变形的原因,并就典型坡体截面应用理正软件分析了正常和降雨入渗两种工况下坡体稳定性,同时应用Flac3d有限差分软件研究了坡体变形特征,对比理正软件稳定性分析结果和数值模拟变形规律可以得出该土质边坡不能满足稳定性需求,并提出相应的边坡加固措施。

Taking the soil slope of the asphalt mixing station of Laohekou Highway Bureau as an example,the slope deformation is analyzed according to the surrounding engineering geological conditions. And the stability of the slope under normal conditions of normal and rainfall infiltration is analyzed by using the software of the typical slope section. At the same time,the deformation characteristics of the slope are studied by Flac3 d finite difference software. The results of the analysis of the stability of the software and the numerical simulation of the deformation can be concluded that the soil slope can not meet the stability requirements,and put forward the corresponding slope reinforcement measures.
