Method for determining side slope critical drainage water line on basis of monitoring

Abstract

The invention relates to a treatment method for determining the position of a landslide drainage water line simultaneously on the basis of the underground water level and displacement monitoring data and coupling analysis. The method for determining the side slope critical drainage water line on the basis of monitoring comprises a first step of landslide monitoring section and monitoring point selection and determination, a second step of installation and arrangement of landslide underground water level and displacement monitoring devices, a third step of real-time monitoring and treatment of the underground water level and displacement, a fourth step of determination of the landslide underground water dynamic increment displacement response rate, a fifth step of determination of a landslide underground water dynamic increment displacement response ratio and a time sequence curve of the landslide underground water dynamic increment displacement response ratio and a sixth step of determination of the landslide critical underground water drainage water line. The landslide drainage water line is obtained by utilizing underground water dynamic increment displacement response ratio parameters so as to treat landslide with underground water serving as a leading trigger factor, the relations between the real landslide water line and a landslide stability state can be reflected visually, and effectiveness and practicality of the method are embodied.

Description

technical field [0001] The invention relates to a treatment method for determining the position of a landslide drainage water level based on groundwater level and displacement monitoring data and coupled analysis, in particular to a method for determining and controlling the critical water level of groundwater drainage under the condition of ensuring the stability of the landslide. Background technique [0002] As one of the most destructive and dangerous geological disasters, landslides are the key to disaster reduction and prevention in a timely and effective manner. Among them, selecting and determining feasible and effective prevention and control programs and measures is the primary task in the process of landslide control. Water-induced landslides account for a large proportion of landslide disasters, and they are very sudden and destructive. Therefore, how to scientifically and effectively prevent and control such landslides has extremely important significance and va...

Problems solved by technology

The determination of the critical groundwater level by such methods is based on the determination of reasonable constitutive relations and accurate physical and mechanical parameters of the soil layer, but it is difficult to obtain accurate physical and mechanical parameters of rock and soil due to the limitations of sampling and test conditions. It is difficult to truly reflect the actual situation of the landslide slope, and the results are prone to large errors due to the above factors, the "black box" of the finite element software and human factors, and there are also limitations such as cumbersome calculation process, large calculation amount and long calculation time sexual problems
