Those solutions not only consider the characteristics of the favorable differences of the rock strength in press and tensile,but also the intermediate principal stress and the nonlinear failure of rock.
采用岩石非线性统一强度理论考虑了岩体的塑性软化特性,利用衬砌与围岩的位移协调条件,对地下圆形洞室进行了弹塑性分析,获得了圆形洞室的应力,洞室变形及塑性区半径的解,这些解既考虑了岩石拉压强度相差较大的特点,又考虑了中间主应力效应及其区间性;既反映了岩石的非线性破坏特征,又可以推广到岩体及节理岩体之中去,有一定的理论及工程应用价值。
