引水口结构三维有限元分析

水工建筑物的结构计算一般都可以通过传统的结构力学法解决，但遇到如开孔、异形体型等特殊问题时，传统结构力学的方法难以准确的反应其受力特性，需要通过有限元方法解决。本文以大西沟管道引水工程冬季引水口为例，通过传统结构力学法和有限元法对比分析计算，明确了边墙开孔处结构受力情况。

Three-dimensional Finite Element Analysis of the Irrigating Gate Structure

The structural calculation of hydraulic structures generally can be solved by the traditional method of structural mechanics,but the traditional method of structural mechanics can hardly reflect its mechanical characteristics such as tapping,deformed shaping and other special problems,so finite element method is re-quired.The study used the irrigating gate of the Daxigou Pipeline water diversion project in winter as an exam-ple,and clarified the structure stress distribution of the tapping on the side wall by contrastively analyzing as well as calculating the traditional method of structural mechanics and the finite element method.
