摘　　要：文章基于工程勘察报告和桩基原体试验方案,选取代表性场地进行了PHC桩试验施工,并对其分别做了低应变法桩身完整性检测,高应变法抗压承载力试验,以及单桩竖向抗压承载力和单桩竖向抗拔承载力静载试验。桩基原体试验成果表明,PHC桩在本工程中是适应的,其承载力和桩身完整性等满足桩基原体试验任务书要求,为后续的工程桩设计和施工等提供了依据性资料。Based on the engineering investigation report and the pile foundation prototype test scheme,the representative site was selected to carry out the PHC pile test construction.The pile integrity test was conducted via the low strain method,as was the compressive bearing capacity test via the high strain method.Additionally,the static load test measuring the vertical compressive bearing capacity and vertical uplift bearing capacity of each individual pile was undertaken.The results of the prototype test of the pile foundation show that the PHC pile is suitable for this project,and its bearing capacity and pile integrity meet the requirements of the prototype test of the pile foundation,which provides the basis for the subsequent engineering pile design and construction.
