Landslide is one of the common dangerous situations of embankment in lake area.It generally develops rapidly with deep sliding surface and is difficult to control.Combined with engineering examples,this paper analyzes the causes of landslide,calculates the position of sliding surface by using static cone penetration test technology and theoretical analysis method,and puts forward a comprehensive treatment scheme of filling pond to control source,block stone to fix foot and wooden pile to prevent sliding.The theoretical analysis method is used to analyze and calculate the stability of sliding along the existing sliding surface,shallow sliding along the pile top and deep sliding along the pile bottom,so as to verify the reliability of the treatment scheme,which can provide some reference for the comprehensive treatment of similar landslides.
