水土保持上一种通过降低坡度防止不稳定坡面发生滑坡等重力侵蚀的沟坡防护工程。 削坡（scaling）主要用于防止中小规模的土质滑坡和岩质斜坡崩塌。削坡可减缓坡度，减小滑坡体体积，减少下滑力。削坡的对象是滑动部分，当高而陡的岩质斜坡受节理缝隙切割，比较破碎，有可能崩塌坠石时，可剥除危岩，削缓坡顶部。
当坡高、坡型、地层条件相同时，路堑边坡的稳定性较削坡的稳定性差。
With same stratum, slope height, slope type, the cutting slope is inferior to the sharpen slope in stability.
天然边坡在削坡工程施工阶段或竣工后，往往形成上下部不同坡度的边坡。
During or after cutting of natural slopes, different gradients of slopes are usually formed on the upper part and the lower part.
对滑裂面固定的边坡进行削坡时，关键在于何处削坡使得土方量最小且边坡具有预期的稳定程度。
The key to the cutting method on a slope with a fixed slide surface is where to cut in order to obtain the minimum earthwork and make the slope reach an anticipated stability.
