随着交通运输的发展,越来越多的公路修建在地质环境背景较为复杂的基岩山区,因而,边坡的变形破坏也成为道路工程最主要的病害类型之一,选取某山区公路一段岩质岸坡作为研究对象,通过对边坡工程地质条件、岩体结构特征及变形破坏迹象等研究,分析总结工程区边坡变性破坏模式及其力学机制,初步判断其稳定性,结合室内计算结果,综合分析判断边坡岩体的自稳性,并提出相应的防治建议。研究结果表明,工程区岸坡破坏模式主要为滑移式和倾倒式,自稳性较差~差。
隨著交通運輸的髮展,越來越多的公路脩建在地質環境揹景較為複雜的基巖山區,因而,邊坡的變形破壞也成為道路工程最主要的病害類型之一,選取某山區公路一段巖質岸坡作為研究對象,通過對邊坡工程地質條件、巖體結構特徵及變形破壞跡象等研究,分析總結工程區邊坡變性破壞模式及其力學機製,初步判斷其穩定性,結閤室內計算結果,綜閤分析判斷邊坡巖體的自穩性,併提齣相應的防治建議。研究結果錶明,工程區岸坡破壞模式主要為滑移式和傾倒式,自穩性較差~差。

As the development of transportation , more and more of the highway was build in complex geological environment background of bedrock mountains , as a result , the deformation and failure of slope become one of the most main types of disease in road engineering , the research object of this article is a certain rock slope on a certain mountain highway , by studying the geological conditions , rock mass structure characteristics and the deformation and failure signs of the slope engi -neering, summarizes the existing modified failure mode and the analysis on mechanical of the slope to determine the initial the stability of the slope , in combination with indoor calculation results , comprehensive analysis to determine the stability of slope rock mass , and puts forward corresponding Suggestions of prevention and cure .The research results show that the mainly failure mode of the existing bank slopeis slippage and dumping , the stability of the slope is poor ~worse poor .
