摘要
本文采用等效应力与薄层单元相结合的方法,解决了拱坝有限单元法分析中应力数值的不稳定问题;所建议的方法为有限单元法在拱坝设计中的应用提供了有效的途径.
In the FEM solution of arch dams, the value of stresses changes with the variation of dimensions of elements markedly. In order to overcome the unstable character of the stresses due to the numerical method , a technique of combination of equivalent stress and thin-layer element is proposed. The practical application to a high arch dan shows that the suggested technique provids an effective way for the use of FEM in the design of arch dams.
