针对目前气垫式调压室体型设计尚无成熟方法可依的情况,基于国内已建工程的气垫式调压室设计资料,采用参数统计分析方法建立了相关参数间关系,拟定了各体型参数取值,并按参数拟定的方便程度逐步介绍各体型参数的拟定方法。同时,比较分析了基于稳定气体体积与基于稳定断面面积的两种体型设计方法的差异。最后以阴平水电站为例,完成了其气垫式调压室的体型设计,且大幅减小了方案拟定阶段的体型设计工作量。
In view of the fact that there is no mature method for the body design of air-cushion surge chamber at present, based on the design information of the air-cushion surge chamber in the built-in project in China, the relationship between the relevant parameters is established by means of statistical analysis of parameters. Value, and according to the convenience of the parameters drawn step by step to introduce the body shape parameters of the proposed method. At the same time, the differences between the two methods of volumetric design based on stable gas volume and stable cross-sectional area are compared and analyzed. Finally, taking Yinping Hydropower Station as an example, the body design of the air cushioned surge chamber was completed, and the body design workload of the scheme drafting stage was drastically reduced.
