拱坝工程实例分析

Example Analysis of Arch Dams

针对高拱坝的应力控制标准的课题，对若干已建的和待建的高拱坝，采用不同的有限元方法和计算条件进行了应力分析，并做了地质力学模型试验研究．其目的是：研究高拱坝坝体应力的分布规律；主要针对线弹性和非线性研究有限元方法计算高拱坝应力的成果差异；研究各种提出有限元应力控制标准的方法和模型试验的控制标准．

To counter the project on stress control criterion of high arch dams, the authors analyze the stresses of some arch dams constructed or to be constructed using different finite element methods and calculat-ing conditions. Research on geo-mechanical rupture model tests is done as well. The purposes of this study are: To study the stress distribution of high arch dams; to study the differences of stress results of high arch dams obtained from different finite element methods especially of linear and nonlinear; to study various ways to suggest stress control criterion of finite element methods and stress control criterion of model test.
