泵站机墩是整个机组的基础,常用的大、中型立式轴流泵机组的机墩型式有井字梁式、纵梁牛腿式、梁柱构架式、环形梁柱式和圆筒式。引黄供水工程武陟泵站正是根据机组特性和泵房结构布置等因素选用了井字梁式机墩,其结构简单、施工方便。本文主要介绍了武陟泵站工程中井字梁式机墩的动力计算,验算机墩在振动荷栽作用下产生共振的可能性,并时振幅进行校核。
Pumping machine pier is the basis of the entire unit, commonly used large and medium-sized vertical axial-flow pump unit pier type with well-beam beam, beam-legged beam, beam-column structure, annular beam column and cylindrical . Wu Huang pumping station is the Yellow River water supply pumping station is based on unit characteristics and layout of pumping stations and other factors selected well-beam beam machine pier, its simple structure, easy construction. In this paper, the dynamic calculation of well pier beam pier in Wupi pumping station project is mainly introduced. The possibility of generating resonance under the load of vibration load is verified and the amplitude of vibration is checked.
