Stability Avalysis And Countermeasures For Landslide Group Of Garang Township Government In Yuanyang County

Ga niang township government resident landslide group south area of the township government is located in the slope zone,denudation,erosion of slope top high for geological hazard prone extents,in recent years,constantly expanding the scope of landslide group,located in the top of the ga niang elementary school playground floor also appear,retaining wall cracking deformation,tension crack extension is more and more obvious,eventually leading to honk niang elementary school above guanyin temple in slope section of the slump,road inside of the retaining wall damage,serious threat to the ga niang elementary school teachers' and students' safety,forced to shunt give way honk niang elementary school.This paper mainly uses geological exploration techniques to investigate and obtain engineering geological conditions and basic characteristic parameters of the landslide area,and then puts forward safe and reliable countermeasures to protect the life and property safety of residents in the landslide area.The main research results are as follows:(1)Geological analysis shows that H1 slider in the survey area is in a stable state;H2-1 slider is in an understable state,while H2-2 is in a basic stable state.H3-1slider is in a stable state,while H3-2 slider is in an understable state.H4 and H5 slider are under stable state.(2)The calculation results of each slide block according to the formula for calculating the folded sliding surface and the transfer coefficient method show that the H1 slide block is in a stable state under the special working conditions of rainstorm and earthquake;The H2 slider as a whole is in an understable ~ unstable state;The H3-1 slider is in a stable state and the H3-2 slider is in an understable state.H4 slider is in an unstable state;H5 slider is under stable ~ unstable state.(3)The countermeasures in order to adopt " prestressed anchor cable anti-slide pile + GuFang dam + drainage engineering of retaining " way of landslide group of disposal,by engineering safety check results show that the ga niang township government resident landslide group of anti-slide pile engineering,drainage engineering,the implementation of the check dam engineering and other engineering,which can effectively control the deformation of the landslide slip,to ensure the overall stability,and bring huge economic benefits for the local.
