Slope Stability Analysis And Engineering Control Research On Regional Planning Slope Of Laizi Ditch Of Dashu New Town At Hanyuan Country

For the complicated land configuration and complex geological structure,problems ofslops in the engineering construction have been attractive nowadays.in recent years,withthe increase of the energy infrastructure development and utilization in our country,we arefacing a large number of complex problems of slops.besides,because of slopedestabilization,which brings about tremendous loss to the country and people’sproperty.Therefore, slope stability analysis and engineering control research areparticularly important.This paper,based on the systematic analysis of the geological conditions for theengineering slop in the Hanyuan Dashu Xinji town, theory analysis and numericalsimulation are combined,systematic analysis and study of the stability analysis，Engineering control measure and the suggestion of changing design are made.The majorstudy works as follow:(1)Clarify the overview of the construction project and geological, hydrogeologicalconditions of the assessmental area such as topography, lithology, geological structure andect.,(2)Describe the causes of adverse geological venues, distribution, development trendsand the degree of harm，and give the technical parameters required for evaluation andremediation.(3)Analysis the morphology of the slope, material composition, destructive manner,the main reason and the main factors affecting the slope deformation.(4)Qualitative analysis, limit equilibrium method and finite element numericalsimulation method are used to calculate the slope stability in natural conditions, heavy rainconditions and seismic conditions.(5)Effective measures in the project are given on the basis of the evaluation of slopestability.(6)Monitoring is studied in the project and after the deformation,and the monitoringmethod is put forward.(7)The changing designs of the slop are studied according to the developmental statusmonitoring during the construction process or after the completion of the construction process.(8)The construction methods and technical requirements are Clarified and thelandslide monitoring program are given.
