Taking the unstable slope of Dongguan Middle School in Lintou Town,Hanshan County as an example,the stability and sliding tendency of the slope are studied by means of engineering geological investigation and evaluation method and limit equilibrium analysis method.According to the present situation and characteristics of landslide,reasonable remediation measures are put forward.The research shows that the landslide is a shallow surface sliding landslide,and the material composition of the landslide is mainly waste soil and residual slope gravel soil.When the landslide is eroded by heavy rain,its state is not stable to unstable.Under the action of rain,the landslide will slip,resulting in its instability.Based on this,it is suggested that the project treatment scheme is slope cutting+drainage+anti-slide pile,which has the characteristics of small amount of soil and rock,small slope cutting range,and basically will not produce on the back edge of the mountain.
