宜兴某土质边坡的稳定性分析与研究

Stability Analysis and Research of Soil Slope in Yixing

甬沪杭原油输送管道宜兴段某处的滑坡是当地地质条件和人为因素引起的。在对该土坡现场调查的基础上，首先利用变分法及参数反算法求出边坡的强度参数，并采用极限平衡理论与有限元相结合的方法对滑坡进行稳定性的计算分析，最后提出了立即停止坡体前缘开挖，采取防渗、排水、截水措施，设置2～3排抗滑桩，加强监测等防治措施。

Landslide of certain Yixing section of Ningbo-Shanghai-Hangzhou petroleum piping was induced by local geological conditions and human factors. Based on the filed survey of this soil slope section, the strength parameter of the slope is found out by means of both variational method and parameter inverse calculation method, the slope stability is calculated and analyzed by limit equilibrium theory and finite element method, and preventative and control measures are finally proposed, including immediate stop of slope front edge excavation, adopting anti-seepage, drainage and water interception measures, setting two to three rows of anti-sliding pillars, and strengthening monitoring.
