Research on methods of investigation and analysis of highway slope stability after flood based on Insar and field investigation

Abstract

The stability of highway slopes after floods is related to the smooth operation of traffic, construction and other related projects along the road. Taking highway slopes in Guizhou Province as the research object, conducting InSAR monitoring and on-site surveys on them, and obtaining a large amount of slope characteristic data after flood, the main conclusions are as follows: InSAR technology can study the influence of highway slope stability after flood, therefore, it saves a lot of manpower and time cost, uses on-site survey method to count the relevant characteristics of the slope along the highway, and uses the index system method to evaluate the risk level of the slope. It is believed that the road slope is prone to poor stability after the flood, and the risk level is higher.
