Characteristics of Hazardous Rock Avalanche Disasters on High and Steep Slopes and Countermeasures for Prevention and Control in Wuling Mountain Area of Chongqing

Abstract

Chongqing Wuling Mountain area has complex geological conditions and frequent geologic disasters, which bring severe challenges to the construction of highways along the route, especially affected by the topography and meteorological conditions in the Chongqing region, the distribution of disaster points is dense, and the disaster management is difficult. This paper takes a highway in Chongqing Wuling Mountain area as an example, fully analyzes the development characteristics of geologic disasters along the route, and concludes that dangerous rock collapse is a typical geologic disaster on the slope in Chongqing Wuling Mountain area. The influencing factors of dangerous rock failure on the slope are divided into three categories: geological conditions, meteorology and hydrology, and slope design pattern, and their influencing mechanisms are elaborated respectively. Finally, 16 high and steep slopes along the route are analyzed in depth, divided into four grades according to the degree of influence on slope safety, and targeted prevention and control measures are proposed. It can provide certain reference for the construction of highway along the Wuling Mountain area in Chongqing.
