The utility model relates to a prestressed cantilever retaining wall, which is characterized in that a plurality of steel sleeves extending from a concrete vertical plate to a concrete bottom plate are arranged in the cantilever retaining wall, and a plurality of high-tension steel cables are introduced into the steel sleeves; the two ends of the high-tension-resistance steel cable in the stretching state are locked and fixed to the cantilever type retaining wall through the locking component, then the cantilever type retaining wall is in a prestress state before soil filling, and part of tension generated in the concrete cantilever type retaining wall due to bending of a vertical plate after soil filling of the retaining wall is completed can be effectively counteracted; and therefore, the overall bending resistance and the overturning resistance of the retaining wall are improved. 本实用新型涉及一种预应力悬臂式挡土墙，通过在悬臂式挡土墙内部设置多个由混凝土立板延伸至混凝土底板的钢套管，并在钢套管内引入多根高抗张力钢索，再利用锁紧部件将处于拉伸状态的高抗张力钢索的两端分别与悬臂式挡土墙进行锁紧固定，继而使得悬臂式挡土墙在填土前就处于预
