| Abstract: | Slope stability is affected by multiple internal and external factors.Based on the engineering geological investigation in the field and literature research,the geological data of 622 typical slopes along the mountainous highway are collected,and a slope geological hazard database is established.According to the database and literature results,a statistical analysis is made on the relationship between instability frequency of slope and influencing factors for slope stability.Results show that the instability frequency of the slope can better show the relationship between the state of slope stability and its influencing factors. |
