摘　　要：运用Solidworks软件建立某特大桥钢板桩围堰和土体环境的三维实体模型,将分析结果与常用简化计算结果以及现场采集数据进行比对分析。结果表明:相比简化的土压力计算方法,Solidworks的钢板桩围堰整体有限元分析结果与实测结果更为吻合。建议在类似桩土结合结构设计中运用包含土壤的整体有限元进行分析,以获得更加符合实际情况的结果。Using Solidworks software, a 3D entity model is established for steel sheet pile cofferdam and soil environment of a super large bridge, and the analysis result and common used simplified calculation results are compared with actual results from real engineering site. The results show that, compared with the simplified calculation method for soil pressure, the integral finite element analysis result of the steel sheet pile cofferdam based on Solidworks is more similar with the measured results. It is recommended to analyze the inlegral finite element including soil to obtain the more similar result with the actual result during design of the similar pilesoil structure.
