摘要研究目的:路堤滑坡作为人类改造自然环境导致的一种工程滑坡，常由于软弱地层、陡坡地段、河流冲刷、坡后汇水、支挡工程不足、老滑坡影响、施工质量欠佳和填方坡率过陡等因素形成。为合理的分析路堤滑坡产生的地质因素和人为因素,确定合理的工程治理方案,本文以某高速公路路堤滑坡为例对路堤滑坡的成因及治理方案进行针对性的分析。
研究结论:（1)造成路堤滑坡的因素较多，合理分析诱发滑坡的关键因子是确定治理方案的关键所在; (2)路堤工程设计以翔实的地质资料为依据，工程施工以严格的工程质量为基础是避免路堤滑坡发生的前提;（3)路堤滑坡往往会造成较大的社会影响，治理方案的确定除考虑工程的安全性、经济性外，还应重点考虑社会影响性;（4)本文关于路堤滑坡成因及治理方案的研究，可为类似工程滑坡的治理提供有效借鉴。

Abstract：Research purposes ： Embankment landslide is a kind of engineering landslide caused by human activities transforming natural environment， which is often formed due to weak strata， steep slope area， river erosion， slope catchment，a retaining engineering problems，influence of old landslide，poor construction quality and steep fill slope. In order to reasonably analyze the embankment landslide geological factors and human factors，determine the reasonable project management plan， this paper takes a highway embankment landslide for example， analyzes the embankment landslide causes and treatment scheme. Research conclusions ： (1) Embankment landslide is caused by many factors，reasonable analysis of the key factor is the key to determine the management scheme. (2) Embankment project design is based on detailed geological data，and engineering construction is based on strict engineering quality， which is the premise to avoid embankment landslide. (3) Embankment landslide tends to form a larger social impact. In addition to considering the safety and economy of the project，the determination of treatment scheme should also consider the social impact. (4) This paper on embankment landslide causes and treatment scheme，can provide effective reference for similar engineering landslide governance.

Key words： expressway embankment landslide treatment scheme
