摘　　要：分析了先张法预应力混凝土波型板桩自身截面原形的力学性能,克服了以往将波形板桩截面等效简化为工字型截面的计算过程复杂繁琐且易产生误差的缺点,新的计算分析方法较以往等效截面计算方法更加科学合理,过程简单清晰,结果误差小。同时结合理论分析进行波型板桩抗弯和抗剪力学试验,对比理论计算结果与力学试验数据,两者吻合较好,验证了理论分析方法合理可靠。The mechanical properties of the original sections of pre-tensioned pre-stressed waveform sheet piles were analyzed. I-shaped It overcame the problems in the equivalent simplification of corrugated sheet pile＇ s sections into sections, whose process was complicated and easy to produce calculation errors. Compared with the previous equivalent section calculation method, the new method is more scientific and reasonable, and the calculation process is simple and clear, which could produce more accurate results. Bending and shearing mechanical tests of the corrugated sheet piles were carried out in combination with theoretical analysis. A comparison of the theoretical calculation results and the mechanical experimental data analysis showed that they were in good agreement, which proved that the theoretical analysis method is reasonable and reliable.
