本文探讨高灌站分基型泵房机墩的设计方法及存在问题。其中,机墩外形尺寸拟定、水平横力对机墩设计的影响、机墩动力参数的频段划分等问题,是对一般设计方法的深入和补充。文中算例为本方法的应用例证,并从中引出简化设计方法。 This paper discusses the design method and existing problems of sub-base pumping machine piers in high-irrigation stations. Among them, the development of the outer dimensions of the pier, the influence of the horizontal lateral force on the pier design, and the frequency division of the dynamic parameters of the pier are the in-depth and complementary aspects of the general design method. The examples in this paper illustrate the application of this method and lead to simplified design methods.
