Abstract

Abstract

Regular geological hazards monitoring is very difficult in southwestern mountainous area, due to steep terrain, abundant plants, rainy and foggy weather. On the basis of geological hazards survey, a comprehensive monitoring network has been established. Regular geo-hazards monitoring devices, such as telescopic displacement meters and stressometers, are installed to monitor relative displacement of ground cracks and stress in base of perilous rock respectively. Static and real-time GPS, as well as corner reflector interferometry (CR-InSAR), are applied to monitor ground movement of perilous rocks. In order to obtain regional deformation, high coherence InSAR is adopted to investigate and detect geo-hazards. The Yangjiao monitoring network achieves high-resolution and real-time monitoring, and the methods applied are essentially in agreement with movement results.
