Study On Geological Disaster Evaluation And Protection Countermeasures Of Xituanshan Remain In Jilin City,Jilin Province

Xituanshan Remain in Chuanying district Jilin city,Jilin province rural village of jixing facility with joy in the camps in the Xituan mountain[1],is a three thousand-year-old former cultural sites of the Bronze Age of primitive society.However,due to the early large-scale mining,digging sand and soil,building roads and houses and other human factors as well as wind erosion,rain invasion,temperature difference,biological and other natural factors,xituanshan site has been damaged to different degrees,and geological disasters such as landslide and collapse may occur at any time.Affected by two consecutive heavy rains in July 2017,the mountain on the east side of the south side of the site collapsed,posing a serious threat to the safety of the site.Geological disaster investigation and cultural relic protection are extremely urgent.Based on field geological survey and laboratory test,the engineering geological conditions,types and causes of geological hazards of xituanshan site are analyzed and studied in this paper.During the field investigation,6 groups of rock samples were collected at the site.Physical and mechanical parameters of the rock were obtained through laboratory tests.The stability of xituanshan site was analyzed and calculated by using the Swedish arc integral model.The main cause of geological disasters is the serious weathering of the slope and the fragmentation of the rock mass.Based on the analysis and stability calculation of the site engineering geological conditions,the comprehensive protection measures such as slope foot masonry,anchor reinforcement,soil compaction and drainage facilities were adopted to reinforce and protect the Xituanshan site to prevent geological disasters and further damage of the site.
