摘　　要：高速公路在路堑边坡开挖施工过程中,经常会出现滑坡问题,由于开挖临空面后路堑边坡防护不及时,特别是在雨季,因边坡稳定性不足而引发的塌方事故时有发生,给工程造成了巨大的经济损失,严重时还会造成生命危险。对于防治边坡失稳等地质灾害,工程技术人员多年开展研究实践,其中有不少成熟的思路和技术。本文结合湖南地区成功的山体滑坡勘察案例,研究分析芷江至铜仁(湘黔界)高速公路滑坡成因,并对边坡进行稳定性定量分析,提出了合理可行的治理方案。During the excavation and construction of highway cutting slopes,landslides often occur.Due to the lack of timely protection of the cutting slopes after excavation,especially in the rainy season,collapse accidents caused by insufficient slope stability often occur,causing huge economic losses to the project and even life-threatening situations.For the prevention and control of geological disasters such as slope instability,engineering and technical personnel have conducted research and practice for many years,among which there are many mature ideas and technologies.This article combines successful mountain landslide survey cases in Hunan region to study and analyze the causes of landslides on the Zhijiang Tongren(border between Hunan and Guizhou)expressway,and quantitatively analyzes the stability of slopes,proposing reasonable and feasible treatment plans.
