Risk and Stability Assessment of Expressway Slope Cutting Construction
This paper comprehensively analyzes the construction risk of a highway project,studies and formulates the corresponding slope protection measures,and further evaluates the slope stability.At the same time,the slope deformation is monitored by the actual reinforcement method.The results show that most of the slopes are in an unstable state,but after reinforcement,the deformation of the slope is significantly less than that of the unreinforced slope,and the deformation tends to be stable with the passage of time.Therefore,it can be concluded that the slope gradually enters a stable state after construction,and the reinforcement methods such as bolt support,shotcrete and anchor concrete and retaining wall are effective.
