摘　　要：目前广泛使用的预应力高强混凝土管桩,因缺乏深入的试验研究,承载能力未能得到充分利用。采用静载与高应变(PDA)相结合的方法,对管桩极限承载力进行了大量的检测试验。综合理论分析,提出了相应的勘察设计参数和施工控制参数,使管桩可利用的承载力比目前提高20%以上,可普遍降低工程的综合造价。The design ultimate bearing capacity of prestressed high strength tubular pile is not used fully in engineering practice, for the lack of experimental data. A lot of static load tests on the ultimate bearing capacity are done. Based on the test and analyses, the parameters for the reconnaissance design and construction control are put forward, with which the design bearing capacity of the tubular pile can be increased by twenty percents, and the integrate coast most of engineerings can be decreased.
