小浪底水电站地下厂房尾水叉洞结构分析

Tailrace Tunnels Fork Area Structural Analysis of Underground Plant in Xiaolangdi Hydropower Station

尾水叉洞是小浪底地下水电站的重要组成部分，其结构设计安全与否是电站建成后能否正常运行的重要因素。本文针对尾水叉洞在施工、运行期可能出现的情况，运用三维有限元法对其整体结构进行了分析，结果表明小浪底电站尾水叉洞设计合理，满足工程需要。

Bifurcated tunnels Fork Area is the important part of the diversion tunnel of Xiaolangdi hydropower Station , The safety of structural design is one of the important factors for the station working normally.was made by the use ofthree dimensional FEM in consideration possible conditions during construction and workingperiod. The structural analysis.The three dimensional tinite element is used to analyze the whole structure,and the results of the analysis show that the design is reasonable and satisfied the engineering need.
