摘要

新疆布仑口水电站有压发电隧洞末端钢岔管最大设计水头为750m,钢岔管水头(H)和洞径(D)的乘积(HD)值为2 400m2,属于典型的超高水头钢岔管,初选钢岔管管材的强度高、钢板厚度大,管径较小,从而增大了制作加工的难度。合理体型的钢岔管对发电系统安全运行非常重要,然而影响钢岔管管壁应力的因素较多,为了提高钢岔管的体型优化效率,通过钢岔管参数化设计平台快速建立模型,再导入有限元计算软件中对钢岔管体型进行优化分析,以达到降低制作难度、质量风险及工程投资目的,亦为今后水利工程中的钢岔管优化分析提供了借鉴。
        The maximum design head of the steel bifurcated pipe at the end of the pressurized power tunnel of Bulunkou Hydropower Station in Xinjiang is 750 m,and the HDvalue of the steel bifurcated pipe is 2 400 m2.It belongs to the typical super high head steel bifurcated.Therefore,the reasonable type of steel bifurcated pipe is very important for the safe operation of power generation system.However,there are many factors affecting the stress on the wall of steel bifurcated pipe.Generally,the selected steel plate of steel bifurcated pipe has some properties,such as high strength,larger thickness and smaller pipe diameter,which increases the difficulty of manufacture,processing and construction.Through the parametric design platform of steel bifurcated pipe,the model was established quickly,and then introduced into the finite element calculation software to optimize the shape of the steel bifurcated pipe,so as to reduce the thickness of the pipe wall,reduce the difficulty of production,quality risk and project investment.Therefore,it can be used for reference in the future optimization analysis of steel bifurcated pipes in hydraulic engineering.
