摘要

针对PHC管桩偏移、倾斜甚至断裂等质量问题，结合津秦铁路客运专线的施工，介绍了管桩在实际施工中沉桩工艺的选择及管桩施工质量控制办法，指出PHC管桩能够有效提高地基承载力，满足路基沉降控制标准。%According to some quality problems of the PHC pipe pile, including the deviation of the pipe pile, the inclination and cracks, the pa- per, combining the construction in Tianjin-Qinhuangdao passenger special line, introduces the selection of the sinking piles and the quality con- trol methods of the pipe piles in the factual construction, and points out PHC pipe pile can improve the foundation loading capacity of the PHC pipe pile, so it meets the standards of the subgrade settlement control.
