| This paper takes the landslip of Lvchun County,as a research object.Base on the engineering geological background,the characteristic of development,producing reason, distribution rule and induce factor,the paper studies the landslip of formation mechanism and control the hazards.According to the landslip development feature and mechanism analysis,provide the suggestion of governing the hazards and country construction.The thesis based on field geologic investigation,laboratory tests,statistic analysis,geomechanical analyzing and so on,pass to the engineering geological background of the landslip in Lvchun from nature geography background, landform feature, stratum lithology feature, geological construct,groundwater, neotectonic, earthquake and the characteristic of development,distribution in Lvchun are analyzed in this thesis from development law and feature.This essential research are listed as follow:1,Affecting factors of landslip in Lvchun as follow:climate humidity, incompact rock and soil layer, landform gradient, groove erosion, flabbiness configuration, surface water,groundwater activity, neotectonic and earthquake and man's engineering activities etc.2,Formation mechanism of landslip in Lvchun:①Incompact rock,groove erosion,provide material for landslip in Lvchun;②Landform gradient 20°to 48°is helpful for landslip development;③There are three flabbiness configuration for landslip production;④The water reduce stress in soild grain because of the climate humidity,precipitation,suface water,grounderwater activity;⑤Man's engineering activities affect the landslip stability and so on.3,Bing forward the final reasonable administer measure suggestion for the governing the hazards in Lvchun county. |
