摘　　要：通过分析高强预应力混凝土板桩截面的抗弯系数的3种不同计算方法,探讨了板桩截面形状、尺寸与抗弯系数之间的关系。与现有的其它类似板桩产品相比,新研发的高强预应力槽形板桩有效提升了截面抗弯系数,提高了混凝土板桩的抗弯弯矩和抗裂弯矩。研究成果将对高性能预应力混凝土板桩优化设计和施工具有指导意义。By analyzing three different calculation methods of the bending coefficient of the section of high-strength pre-stressed sheet piles,the relationship among the shape,size,and bending coefficient of the pile＇s section was discussed. Compared with other similar products,the newly developed high-strength prestressed slotted sheet piles have their sections＇ bending coefficient effectively improved,and their bending moment and crack-resistance moment improved as well. The research results will provide guidance for the optimization design and construction of high performance prestressed concrete sheet piles.
