【摘要】 本文讨论将混凝土视为正交各向异性体，用非线性有限元法结合实验研究，对带裂缝的混凝 土试块进行了分析，并对我国已建工程牛路岭空腹重力坝假定坝踵与坝基接触面存在裂缝进行分 析计算，从而得到一些有益的结果。更多还原

【Abstract】 This paper, taking the concrete as an orthogonal anisotropic solid, and ad- opting the nonlinear FEM method integrated with experimental studies, has an- alyzed the concrete specimen with fracture, and then applied the result obtained to analyze and calculate the existing Chinese Niululing hollow abdomen gravity dam with an imaginary fracture on heel along the contact surface between the dam and foundation. Some valuable results have been obtained.更多还原
