基于ABAQUS的三维有限元在闸站分析的应用

Application of Three-Dimensional Finite Element Based on ABAQUS in the Analysis of the Combined Sluice-Pump Projects

以平原地区某闸站结合工程为例,利用ABAQUS软件建立闸站与地基三维有限元模型,从设计洪水位、校核洪水位、地震3种工况对闸站结构进行有限元分析,计算相应工况下的结构位移场和应力场。由结果可知,在3种工况下闸站结构的空间位移较小,应力变化都在规范允许范围内,整体结构的稳定性较好。分析表明,三维有限元分析能准确、直观反映闸站结合工程的空间受力、位移状况,为今后解决复杂空间结构问题提供有效的方法。

This paper selects a combined sluice-pump projects in plain area as an example,establishing a finite element model of sluice station and foundation by ABAQUS software.The structure of sluice-pump projects is analyzed by finite element analysis from three conditions of design flood water level,check flood water level and earthquake,and the structural displacement field and stress field are calculated under each working condition.According to the calculation results,under the three working conditions,the spatial displacement of the sluice-pump structure is relatively small,and the variation of stress is within the allowable range of specification,and the overall structure has better stability.The analysis shows that the 3DFEM can accurately and intuitively reflect the space load and displacement of the sluice-pump projects,and provide an effective way for solving the complex spatial structure problems in the future.
