Based On Numerical Calculation Of Optimal Layout Method Research Of Slope Displacement Monitoring

The stability of the slope is closely related to people’s production and life, it is necessary to evaluate slopes’ stability with corresponding method. Slope stability monitorings of slope are important means for its stability evaluation, and the displacement monitoring is an important content which contains rich monitoring information. Displacement monitoring can visually reflects the deformation of slope, can forecast the recent deformation of the slop with monitoring data by corresponding forecast model, can also provide parameter for inverse computation. At present, scheme of displacement monitoring parts is still rely on expert experience and engineering analogy, which is lack of specific theory basis, so monitoring points setting adopts the qualitative scheme, which is the lack of quantitative analysis. Therefore, this paper qualitatively research method of monitoring points with on numerical calculation. The main research contents are as follows:(1) Analyse the effection of measurement error on slope stability analysis and parameter inversion, and puts forward the principle of slope displacement monitoring points’ setting considering the characteristics of slope engineering.(2) In order to know the details of the slope failure process, put forward the "incremental method" to realize the slope strength reduction method of calculating the safety factor, and write the corresponding program.(3) Use displacement field analysis method to discusses the slope monitoring points’ setting scheme.(4) Put forward that analyse the grey correlation between displacement serial and strength reduction coefficient to determine the setting of displacement monitoring points with the actual working condition.(5) The sensitivity analysis is proposed to choose monitoring displacement monitoring.
