摘要
计算推导出Drucker-Prager(简称D-P)屈服准则与Mohr-Coulomb(简称C-M)屈服准则5种不同拟合条件下,5个屈服圆面积的大小关系;并采用5种屈服准则计算得出瀑布沟尾水隧洞出口天然边坡破坏发育状况,其破坏发育程度与C-M不等角六边形屈服面内角边长与外角边长比值i介于33/(2π)~1.0之间时,5个屈服圆面积的大小关系较为吻合,且i值更接近33/(2π).
-Fhe areas of the five yielding cirdes in different fit conditions of Dmcker-Prager(D-P for short) yielding criterion and Morh-Coulomp (C-M for short) yielding criterion are calculated and inferred.Failure areas of Pubugou natural slope computed by the five yielding criterions fit in with relation of the five yielding surfaces when the value of c approaches,which is the ratio of intemal angle legth to extemal angle length of C-M hexagon.
