【摘要】：針對傳統(tǒng)計算方法不能反映塊基式泵房復雜空間結構相互作用的問題,為了解泵房整體結構工作機理,以江蘇省某塊基式泵房結構為例,基于有限元理論,借助ANSYS軟件建立了包含流道層、電機層、廠房結構及地基的塊基式泵房和地基整體結構三維有限元模型,模擬了泵房結構在各荷載組合工況下的工作性態(tài)。考慮了鋼筋混凝土材料的彈性、土體材料的彈塑性及結構和地基接觸面的非線性行為,得到了泵房結構的位移、應力及基底應力分布,為塊基式泵房結構的設計和施工提供了重要技術依據(jù)。
[Abstract]:In order to understand the working mechanism of the whole structure of the pump house, the traditional calculation method can not reflect the interaction of the complex spatial structure of the block pump house. In order to understand the working mechanism of the whole structure of the pump house, the structure of a certain block pump house in Jiangsu Province is taken as an example, based on the finite element theory. With the help of ANSYS software, a three-dimensional finite element model of the block base pump room and the whole foundation structure including the runner layer, motor layer, powerhouse structure and foundation is established, and the working behavior of the pump room structure under various load combination conditions is simulated. Considering the elasticity of reinforced concrete material, the elastic-plastic behavior of soil material and the nonlinear behavior of structure and foundation interface, the displacement, stress and stress distribution of pump house structure are obtained. It provides an important technical basis for the design and construction of block base pump house structure.
