摘要

在公路营运期,某边坡坡面出现3条裂缝,裂缝造成坡面一坟墓严重错动变形及截水沟破坏,对公路营运构成安全隐患,且潜在社会影响较大。为查明边坡坡面裂缝成因,分析边坡稳定性并提出相应处治措施,采用地质调绘、地质钻探及理论分析等手段对该边坡开展了相应的研究工作。研究得出:边坡整体稳定性良好,坡面裂缝均是局部坡体产生的浅表层蠕动所致。在查清边坡裂缝成因的基础上,制定了以变形监测为主、局部坡面加固维护的处治措施,经后期监测数据反馈,边坡稳定性良好。
        During the service phase of a highway,three pieces of cracks appear on the slope,which have caused serious dislocation of a grave and the failure of the truncation ditch and led great danger on the safety of highway and social impact.In order to find out the causes of the cracks,analyze the stability of the slope and put forward the treatment measures,the corresponding studies have been carried out on the slope by means of geological mapping,qualitative drilling and theoretical analysis.It is concluded that the overall stability of the slope is good and the cracks in the slope are the result of the superficial peristalsis produced by the local slope.On the basis of identifying the causes of the slope cracks,the treatments measures of deformation monitoring and the local slope reinforcement are worked out,and after verified by monitoring data,the stability of the slope is good.
