This dissertation also analyzed the problem of casually cutting grading angle , which fluently happens in construction of slope engineering
通过对施工中经常遇到的坡角临时切割问题进行分析，结果表明。
Many cases of excavation and support of high rock slopes were symtematically analyzed , and some conclusions were drawn . there exists stress concentration in grading angle induced by excavation and obvious change of stress and strain on sloping surface , which reduce as the increase of distance to surface . initial stresses have important influence on excavation and support
撇面上的应力应变的靴很大，随着离坡面距离的增加而减小；初始地应力对边坡的开挖支护产生很大的影响，随着初始地应力的增加，开挖坡面回弹位移增大。
