向家坡滑坡综合治理研究

针对渝黔高速公路路堑边坡向家坡滑坡综合治理工程实例，首先通过对该边坡前期滑动及不成功治理过程介绍，结合地表位移监测和详细的地质勘探，准确地判断了路堑边坡滑坡病害性质、滑坡机例，总结了前期治理失败的原因；然后将滑体与前期支挡工程视为桩土复合体进行了稳定性分析；最后制定了临时防治与永久根治相结合的多途径的综合治理方案。成功的实践表明，这是一种既安全可靠、又经济合理的路堑边坡滑坡综合整治措施。

A study of comprehensive control of Xiangjiapo Landslide

In allusion of an engineering case of the improvement of Xiangjiapo cut slope of Yu-Qian highway, this paper firstly describes the sliding of the slope in early stage and unsuccessful controlling works and then it ues the measuring results of ground surface monitor in connexion with detailed geological exploration to judge accuraltely the property and the mechanism of the sliding disater of the cut slope. And on this basis, this paper sums up the reasons of previous unsuccessful improvement and then makes the stability analysis in which the sliding mass and previous supporting works are considered to be a compound body. Finally, the paper draws up a comprehensive multiple-way controlling scheme in which temporary and permanent control of the cut slope are jointed organicly. It is a comprehensive control measure for cut slope sliding, being reliable, rational and economical.
