彭水羊头铺水电站厂房流道三维数模分析

羊头铺电站是重庆市彭水县郁江梯级开发中的中型水电枢纽工程,对该电站的主厂房流道采用非线性有限元方法进行三维数值模拟,分别对正常运行、施工、检修、施工度汛况以及校核洪水等5种工况进行分析,通过数值分析结果获得的不同工况下结构的受力特点,提出该电站的主厂房流道的优化设计建议.

The 3-D Numerical Analysis of the Workshop Flow-way of Yangtoupu Hydroelectric Station in Pengshui

The Yangtoupu hydroelectric station is a key work position of the step developments of Yujiang River in Penshui County of Chongqing City.The method of nonlinear finite element of elastic-plastic is adopted for carrying out the three dimension numerical modeling work on the workshop flow-way of Yangtoupu hydroelectric station.The five force cases are concerned during the numerical analyses processes,which contains the normal running,the constructing and running,the running and checking and repairing and the constructing and sluicing.Based on the results of numerical analyses,some improving suggestions to the design plan of workshop flow-way of Yangtoupu hydroelectric station are proposed.
