四川省道某弃土场病害成因分析及治理措施

弃土场是公路工程的组成部分，由于在设计和施工中得不到应有的重视，经常引发滑坡、泥石流等次生灾害。根据四川省道某弃土场病害治理工程实践，综合有限元分析和极限平衡理论对弃土场边坡稳定性进行评价；在此基础上运用理正岩土计算软件，对弃土场边坡稳定性进行分析并计算边坡下滑推力，提出了相应的治理措施。

Geologic Hazard Cause Analysis and Control Measures of a Spoil Ground in Sichuan Provincial Highway

As a part of the highway engineering, the spoil ground side slope often leads to landslides, debris flows and other secondary disasters due to lack of attention in the design and construction. According to the geologic hazard management practice of a spoil ground in Sichuan provincial highway, using finite element analysis and limit equilibrium theory to evaluate the stability of the spoil ground side slope; on such basis and using Lizheng geotechnical calculation software to analyze the stability of the spoil ground slope and calculate the sliding thrust of slope, and finally put forward the corresponding control measures.
