Abstract: The behavior of PHC pipe piles under lateral load is lack of research now. To analyse the behavior of PHC pipe piles under lateral load by three different shallow foundation treatment methods, including gravel compaction by vibrating, compaction by vibrating roller, vibrating and tamping method, field lateral static load test was carried out. The proper shallow foundation treatment method was determined. To analyse effect on the behavior of PHC pipe piles by different parameters of piles and soils, finite element method was used in simulation. Some clues for choice of proper shallow foundation treatment method were provided. These results were of value, which was useful for design and construction of similar projects.

摘要： 不同浅层地基处理法下PHC 管桩水平承载性状对比尚缺乏研究。通过现场水平静载荷试验，分析了碎石振动碾压法、振动碾压法和振捣法三种地基处理方法中PHC 管桩在水平荷载作用下的受力特点及水平承载力，对比得出了合理地基处理方法。通过三维有限元模拟，分析了桩、土参数的变化对PHC 管桩水平承载性状的影响，为合理地基处理方法的选用提供依据。研究结论具有一定的工程实践指导意义，可为今后类似工程设计和施工提供参考。
