Abstract:In order to realize the dynamic monitoring early warning and timely response to the highway slope and ensure the driving safety a slope monitoring and early warning scheme using IFOA algorithm based on the investigation and analysis of the slope of Gansu Weiwu expressway. Through indoor simulation tests of loess slope the slope displacement-time relation curve under different rainfall intensity was obtained. Then the early warning and classification index of slope based on rainfall intensity displacement time curve characteristics and displacement was proposed and the measures for different warning gradings were put forward. The research results realized the early warning and response of high and steep slope stability detection could ensure the construction safety and provided the basis for the optimization of the high slope design scheme.
