摘　　要：结合实际工程介绍了前板桩后低桩承台结构的应用特点,分析了在实际设计中的技术要点和注意事项。前板桩后低桩承台结构复杂,原有规范不完全适用。结合实际工程,考虑钢板桩变位不能完全复位、低桩承台卸荷等因素,进行三维数值模拟,得到了码头结构主要构件的内力,从桩基与承台连接方式等方面分析这些因素对结构的影响,从而为结构设计和优化提供了依据。Combining with practical engineering, the paper introduced the application characteristics of the front sheet-pile and offside-low pile platform, and analyzed the technical points and considerations in the actual design. The front sheet-pile and offside-low pile platform structure is complex, and the original specifications are not completely applicable.Combining with practical engineering, and considering the factors such as the unloading of low pile dim platform and that the deflection of steel sheet pile cannot be completely restored, it conducted the three- ensional numerical simulation to get the internal force of the main components in the wharf structure, and analyzed the influence of these factors on the structure from the aspects such as the connection mode between pile foundation and bearing platform, which provides the basis for structural design and optimization
