Slope Stability Analysis Under The Condition Of Perennial Water Immersion

In recent years, with the vigorous development of China’s infrastructureconstruction, the slope deformation and failure such as landslides, avalanches andmudslides occurred frequently whitch has caused huge economic losses. In addition to,people’s life and property also suffered huge losses. Many factors affect the slopestability, among them, the role of water is a key factor, each year, and the effect ofwater caused a lot of accidents of slope failure. Therefore carried out under seepageanalysis of slope stability and ensure the safety of the slope is very necessary,moreover it also has practical significance.Firstly, this paper summarizes and analyzes the basic theory of slope stabilityanalysis, it also contrast the method, characteristic and applicable conditions of slopestability analysis, besides it make calculation combined with practical engineering,and according to the calculation results it carring on the analysis appraisal to the slopestability. And then based on fundamental laws of seepage, the paper consider asaturated porous media flow field and stress field interaction effects on slope stability,and explore effective method for solving when Fluid-solid coupling equationsdeduced, in order to provide a theoretical basis for numerical simulation. Furthermore,whether to consider the water through seepage and reinforced front and rear, etc. willgenerate different conditions, then I make numerical simulations under these differentconditions, through them the paper analysis the stability of slope that contains piersand the stability of slope that does not contains piers, according to the calculationresults it carry on the analysis and evaluation of slope stability.Finally, the paper is based on the slope of Chang-Zhang Expressway K254tomake typical calculations partition of cross-section under the method of the paper, andthrough on-site monitoring data to analysis the stability of slope framework protectionand landslide, against the reinforced slope the paper proposed dynamic monitoringprogram of scene and established the monitoring contents, that will provide technicalsupport and security for the smooth progress of the project.
