- Under abnormal climatic conditions, a large number of cutting slope deformation instability problems that plagued expressway operation have become one of the major security issues. The formation lithology, geological structure and other inner factors are closely related to the stability problem of expressway cutting slope during the process of occurring and development, and the meteorological, hydrology and earthquake and other external conditions are also major predisposing factor of slope deformation and development. Based on the Guanghe expressway K66 + 250 ~ K66 + 534 on the right slope engineering geological environment, the process of deformation and deformation history of the different stages of research, think that the cataclastic rock mass slope failure slip having an arcuate surface at the macro Features, and at the micro exhibits along the slope failure modes have jointed, level of development jagged or stepped features. In addition, this paper also puts forward a specific proposal for the prevention and treatment of the type of expressway slope diseases. Construction of expressway is gradually extending to mountainous ares featured by such complicated geological conditions that high and steep slopes are formed along it. Under complicated geology, landforms and geological hydrology, many types of troubles concerned slopes come into being in service and the damages caused by deformations of cutting slope have become one of the most serious security issues that beset the expressway service. Based on a close relationship between occurrence and deterioration of deformation on cutting slope and the inner factors such as features of rock in stratum, the geological structure and so on so forth,some extrinsic factors like metrology , hydrology and construction become the main incentives(1,2) causing deformations and deterioration of cutting slope. Under a complicated geological condition in rainy and hot area, deformation of slopes formed by broken rocks become one of the common geological hazards in the period of expressway service in hilly areas. This paper, exemplified by the treatment of right slope on section K66+250~K66+534 in Gangue Expressway, made a detailed analysis of destructive mechanism caused by deformation of slopes formed by broken rocks Under a complicated geological condition in rainy and hot area, and proposed in particular a reasonable suggestion for treating slope hazards, which provided experience that can be learnt to employ in the prevention and treatment of the similar type of slope hazard in similar areas.
