摘要
使用大型三维非线性有限元程序(TFINE),对拉西瓦拱坝-地基系统进行了三维弹塑性有限元数值模拟,对该拱坝地基系统,在正常荷载下的位移和应力进行分析。并在此基础上,进行了整体稳定分析和大坝超载能力分析。结果表明,拉西瓦拱坝的位移、应力和超载稳定能力均达到稳定要求,但部分基础需进行适当加固。
This paper presents the elastoplastic numerical results of Laxiwa arch dam-base system by employing Three Dimensional Non-linear FEM, TFINE code. The displacements and stresses of the dam were analyzed. Then the stability and overloading analysis of the dam were made. The results show that the displacements, stresses and the overloading capacity of Laxiwa arch dam meet the requirement of stability.
