Based on the present practical application of the classical limit analysis method in slope engineering,some urgent problems in the limit analysis method of slope stability are discussed.In view of the problems such as excavation and unloading in the districts of high ground stress,water filming effect of intercalated clay layer,stability of distorted rockmass slope,and the solid-liquid coupling of seepage and impartment,several ways to solve these problems such as 3-D numeric analysis,integral random method of deformation and stability,equal parameter value treatment that affects the after-effect and environment slope engineering are analyzed.The development prospect of enviromental slope engineering is pointed out and some real cases are provided.
