Study On Landslide Stability Analysis And Anti-slide Piles Based On FLAC3D

With the development of our country’s foundation construction, the study andcontrol design of engineering slope are becoming a hot topic. Recently, anti-slidingpile has been regarded widely as a dominating means of administering landslidegeologic disaster, and it has developed rapidly in homeland and abroad with greatadaptability and sliding strength. Besides, it is possible to construct ant-sliding pilessimultaneously and reduce the time limited for a project.Based on the practical engineering of landslide, the author use the FLAC3D finitedifference numerical calculation software to carry out the numerical simulation oflandslide in the discourse, and on this basis putting forward effective prevention andcontrol measures to prevent and solve the landslide. The main research contentsinclude:1.This paper sums up the domestic and foreign research results of landslide andlandslide related theory, and describes the principle of numerical analysis of FLAC3D,and bring the system analysis of landslide zone formation lithology, geologicalstructure, topography and hydrological geological conditions and discusses thedeformation and fracture mechanism of landslide.2.Study on the influence factors of the slope stability, and the numericalcalculation of two important parameters in the angle of internal friction and cohesionare analyzed.3.To establish a three-dimensional numerical model, through the analysis ofcomplex three-dimensional landslide displacement field, stress field, plastic zonedistribution, combined with the landslide of the typical profile of stress, strain,landslide stability.4.The present situation of landslide focus on local governance and comprehensivecontrol of combined reinforcement measures. The paper concludes to work out withanti slide pile sliding Engineering, combing drainage system plan, biological protectionengineering reduced sliding engineering as auxiliary measures of treatment scheme andnumerical simulation calculation of anti slide pile reinforcement of six programmes,validation of anti-slide pile reinforcement effect.5.Through the analysis of the monitoring data of anti-slide pile, respectively, ofthe moluocun landslide on anti-slide pile deformation and stress of the monitoring, themonitoring data are found in the scope of design, it is concluded that the scheme ii management plan for landslide is reasonable.6. Finally the paper conclude the work and achievements, and puts forward somesuggestions for further study.
