灯泡贯流式机组管型座混凝土结构计算

The Calculation of Bulb Tubular Type Generating Unit Tube Seat Concrete Structure

管型座是灯泡贯流式机组的主要支撑结构,其受力十分复杂。通过三维有限元及结构力学法两种计算方法,对桑河二级水电站厂房管型座混凝土结构进行分析。计算结果表明,管型座混凝土结构尺寸设置合理,配筋可靠,较好的解决了灯泡贯流式机组管型座结构复杂的配筋问题。

The tube seat is the main supporting structure of a bulb tubular type generating unit and its force is quite complex. The powerhouse tube seat concrete structure of the Se San - II hydropower plant was analyzed using both 3D finite element method and structural mechanics method respectively. The calculation results show that the di-mensions of the tube seat concrete structure are rationally designed and its reinforcement is reliable so that the rein-forcement problem of the complex bulb tubular type generating unit tube seat structure was properly solved.
