摘要:: 文章以渝利铁路黄草山滑坡治理工程为研究对象，介绍了滑坡体的地形地貌、地质构造、地层岩性、气象和水文；采用传递系数法的计算方法，对黄草山滑坡进行了稳定分析，得出在路基和隧道通过的地段对滑坡的稳定性不利；采用抗滑桩、锚索桩板墙、排水等综合工程措施对滑坡体进行治理。观测资料显示，治理后的滑坡处于稳定状态，确保了渝利铁路的安全运营。抗滑桩结合抗滑桩、抗滑桩结合锚索桩板墙的双排桩的处理滑坡是一种创新，存在充分的可行性和足够安全性，可供类似工程参考。

Abstract:: Taking Huangcaoshan mountain landslide treatment project of Chongqing-Lichuan railway as an example, the landform, geological structure, stratum lithology, meteorology and hydrology of landslide body are introduced. Stability analysis is taken for the Huangcaoshan mountain landslide by transfer coefficient method. It is unfavorable for the stability of the landslide in the section of the subgrade and tunnel. The anti-slide piles, cable-anchored slab-pile wall, drainage and other comprehensive engineering measures of landslide control can achieve good results. The observation data show that the landslide after the treatment is in a stable state, which ensures the safe operation of the Chongqing-Lichuan railway. The methods of dealing with landslides with anti-sliding piles combined with anti-sliding piles and anti-sliding piles combined with cable-anchored slab-pile wall are innovations that have sufficient feasibility and safety, which can provide reference for similar engineering.
