三峡水电站蜗壳充水加压模型试验研究

Model Test on Filling Pressure Water Scroll of Hydroelectric Power Station of Three Gorges Project

本文采用模型试验的方法对三峡水电站蜗壳及外包混凝土结构进行研究 ,主要研究蜗壳在充水加压条件下浇筑混凝土后结构的受力状态和破坏规律。通过试验 ,初步弄清了蜗壳、混凝土和钢筋三者之间的受力关系。试验结果表明 :在设计荷载下 ,蜗壳与外包混凝土可以共同受力 ,配置的钢筋起的作用较小 ,结构的安全性可以得到保证。

In this paper the scroll and its outside concrete of hydroelectric power station of Three Gorges Project was studied by model test.The main contents are stress state and failure mechanism after concrete is constructed when the scroll filling water pressure.According to the test the relations among scroll,concrete and reinforcement bar is made clear.Under design load The combine action between scroll and outside concrete can be guaranteed and reinforcement bars have not effect obviously.So structure has large safety.
