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。
This article discusses the use of concrete as an orthotropic body, combines nonlinear finite element method with experimental research, analyzes the cracked concrete test block, and evaluates the hypothetical dams of the Niulering fasting gravity dam built in China. There are cracks in the contact surface of the dam foundation for analysis and calculation, so as to obtain some beneficial results.
