摘要： 通过对宣汉县南坝镇某滑坡的专项工程地质勘察工作，查明了滑坡的工程地质条件和基本特征，在此基础上分析了滑坡的形成机制、主要控制因素和诱发因素，对滑坡进行了滑坡稳定性评价，并且提出了有效的防治对策。调查研究表明该滑坡为降雨诱发牵引式滑坡，其治理以抗滑支挡结合地表排水为主。

Abstract: The geotechnical and engineering geology investigation aspects of a landslide mitigation project in Nanba Township of Xuanhan County are presented in this paper. The geological characteristics of the landslide are investigated. The evaluation work on the mechanism of the slide, slide controlling and triggering factors is conducted and the mitigation measures are also presented. The investigation and evaluation results indicate that the precipitation is the triggering factor and the planar slide is the result of excessive rainfall. The mitigation project is therefore focused on the sliding support and installation of the appropriate surface drainage system.
