Determination for the Type of Wujiang River Landslide Based on Forced State

The understanding landslide types from stress state is critical for rational landslide control. In order to determine the landslide type of Wujiang landslide in the Centianhe expansion engineering, in this study, we have analyzed the geotechnical characteristics of the landslide and the monitoring data of slope deformation. Then, the comprehensive inversion of geotechnical parameters for 4 typical sections was carried out respectively based on the suggested values of the mechanical parameters and the parameters of the laboratory test. What’s more,the calculation models of the 4 typical sections was established and analyzed based on Morgenstern-Price method. The analysis shows that slow creep deformation currently exits in the Wujiang landslide. It is probable that the shallow landslide at the leading edge is likely to fracture and collapse, while the whole landslide is less likely to slide quickly. It is most likely to take the slope toe which is in the weak area firstly to slide and then pull the other lands
