为研究填芯对PHC管桩抗弯性能的影响，基于弹性理论及叠加原理，推导出填芯PHC管桩抗弯承载力计算公式；同时对填芯与不填芯PHC管桩进行对比研究。研究结果表明，素混凝土填芯对PHC管桩抗弯承载力约能提高16%，钢筋混凝土填芯对PHC管桩抗弯承载力约能提高35%。该结果可作为水平荷载作用下填芯PHC管桩设计的参考依据。

For the study of the effect of filled core on the performance of PHC pipe pile bending, deduced the formula of flexural bearing capacity of filled core PHC pipe pile via elastic theory and superposition principle, and comparatively studied the PHC pipe piles with filled core and without filled core. The results showed that the plain concrete filled core improved the flexural bearing capacity of PHC pipe pile by about 16%, and the reinforced concrete filling core improved the capacity about 35%. It can be used as a reference for core filled PHC pipe pile design under the horizontal loading.
