三峡水电站左岸厂房10^#机组充水保压蜗壳监测成果分析

The Analysis Of Monitoring Results Of The Spiral Case Of 10^# Turbine In Left Powerhouse In the Process Of the Placement

本文通过对三峡工程左岸电站10^#机组蜗壳保压浇筑的全过程监测,分析了机组蜗壳在施工期加压、保压以及卸压过程中的钢板、混凝土和钢筋的应力状况和钢板与混凝土结合缝的开度状况,得出机组蜗壳在整个加压和卸压的浇筑过程中工作性态正常,应力和变形均在设计允许范围内。

In this paper,the stress distribution and the joint aperture distribution of the spiral case of l 0^# turbine in left powerhouse is analyzed through monitoring of the stress and the joint aperture of the sections of the spiral case in the process of the placement under desirable pressure conditions, the stress and the strain of the spiral case both belong to the allowable design range, which showed that the spiral case of 10^# turbine work normally.
