| 摘 要： | 某高速公路路线通过古滑坡前缘,工程建设需要对滑坡前缘进行开挖可能导致滑坡复活.在现场调查分析的基础上,采用极限平衡理论和变形理论对滑坡在各工况条件下的稳定性状况、应力环境和变形特征进行研究,认为滑坡在前缘开挖和运行期暴雨状态下可能产生复活.在此基础上提出了双排抗滑桩的治理设计方案,并基于变形理论的稳定性评价方法对该方案的治理效果进行了研究,结果表明该方案能有效地改善坡体应力条件并控制坡体整体变形.

| Abstract: | An expressway is designed to pass the front of an ancient landslide, so the leading edge of the ancient landslide has to be excavated according to the requirement of construction, which perhaps induces the reactivation of the ancient landslide. Based on investigation and analysis in situ, using the limit equilibrium theory and the theory of deformation, the stability situation, stress environment and deformation characteristics under all operation conditions are studied. The conclusion is that the ancient landslide perhaps reactivates under the condition of storm when its leading edge is excavated or it is in the long--term usage. On the basis of the study, the measure of dual anti--slide pile is put forward. Afterwards, the effect of the measure is studied with the evaluation method of stability on the basis of the deformation theory. It is proved that this measure can effectively improve the stress conditions of the slope and control the deformation of the overall slope. |
