Study on Joint Load Bearing of Steel Spiral Case and Surrounding Concrete

摘要

Spiral case are important diversion parts of reaction type wheel, this paper adopts finite element method to carry out simulation analysis for spiral case structure of Shuikou hydropower station. Considering five calculation schemes in analysis, under different thickness and materials of cushion, researching stress and deformation distribution law of steel spiral case and surrounding concrete. Analyzing bearing ratio of steel spiral case and surrounding concrete, Research results provides reliable reference for design and construction of steel spiral case.
