摘要
将拱坝及其周围地基作为一个完整的研究对象．按全量型进行非线弹性分析．对不同的应力状态应用不同的强度准则．对不同的破坏状态应用不同的本构方程，并考虑材料的软化．对不同的破坏状态应用不同的弹性矩阵．本文最后给出了非线弹性本构关系分析的框图和一个拱坝非线弹性分析的例子。
Arch dam and its rock foundation are taken as an integral coupling object of study. The constitutives of dam concrete or foundation rock are nonlinear elasticity. Different failure criteria of concrete and rock are used according to different stress state. Different constitutive modules and different elastic matrices are used according to the modes of fracture. The softening section of stress-strain relationship is considered in analysis of crack on arch dam and in rock foundation. Lastly, the flow diagram and a nonlinear analysis example of arch dam are presented.
