Abstract

Based on a large number of detection cases of operation highway slopes, this paper proposed a theoretical calculation model and assessment criteria for assessing the potential risk of highway slope failure. Meanwhile, it explored the main factors and their degree of influence on the technical conditions of highway slopes, and adopted practical projects as an example to predict and analyze the slope risk degree. The analysis results show that the unstable index method based on a large number of slope cases can better reveal the main factors affecting the risk of operation highway slopes. The key factor affecting the highway slope failure is mainly the technical conditions of the slope itself, and the weight of factors such as technical conditions of the slope protection structure, and terrain and landforms of the slope surface has relatively low weight. The utilization of mathematical statistical methods for assessing and grading the potential risk of slope failure has certain rationality, and the calculation misjudgement error of the established potential risk area of slope failure can be effectively reduced.
