Analysis on Deformation Characteristics and Early Warning of Qinshui Pipeline Landslide in Shanxi Province
In order to realize the analysis of landslide deformation characteristics and the accurate evalu-ation of early warning,this paper takes the pipeline landslide at JP11+100m of Jinhou Phase Ⅲ in Qin-shui county as the engineering background,and based on the landslide deformation monitoring data,the landslide deformation characteristics are analyzed by statistical methods,and then the landslide early warning classification research is comprehensively carried out by the cumulative deformation criterion,rate deformation criterion and acceleration criterion.The practical case analysis shows that although the cumulative deformation at different locations of the landslide continues to increase,there are some differ-ences in the deformation characteristic parameters,and the warning levels of the four monitoring points are also inconsistent.Among them,one monitoring point has a warning level of Level Ⅱ,and the rest are Level Ⅲ,resulting in the comprehensive warning level of the landslide is Level Ⅲ.Therefore,it is high-ly necessary to control the landslide of the pipeline,and it is recommended to carry out the prevention and treatment of the landslide as soon as possible.
