| Da fu forest park was called oxygen bar of Panyu. Recently, the occurrence of landslides on the west side of the mountain park, Landslide Divided into two deformable bodies, south east and north west, has There is a high-voltage tower in the upper part of the North West deformable body. The lower part of the landslide of Yu Shan west Road and new east of high-speed, Currently landslide trend still continues to expand, threatening the lives and property of the upper electrode mountain road tower and below and pedestrians. So the Da fu Mountain Forest Park landslide hazard assessment and stability analysis is extremely necessary.This article expounds the significance of the landslide hazard assessment, the risk analysis and the stability assessment of the landslide at home and abroad.,and the risk analysis and stability assessment of Forest Park landslide in the doctor mountain were determined.The field investigation of 2 landslides points in the study area is carried out, and the risk of each point is more accurate field evaluation afterconsulting a lot of the regional geological data and the development history of landslides.Finally, the parameters of the factors of the risk assessment and stability analysis of geological hazard are extracted.Additionally, this article analysis the stability of the landslide by GEO-STUDIO.,in cites of North West morph body. Using Seep / W module analyzes the natural state of the pore water pressure of landslide. and coupled with its analysis and Sigma / W module, resulting the slope displacement state, derivating of slope cut position. Finally using Slope / W module calculated stability coefficient of landslide, analyzing the landslide deformation trend. By fuzzy comprehensive evaluation, Landslide analysing hazard assessment results based on the results of stability GEO-STDUIO is same with the evaluation results of the field.so the Da fu forest Park Risk Assessment and stability assessment is reasonable and credible with this method. |
