通过实例工程中预应力管桩的施工和桩基检测经验,以两个批次的试桩试验和一个批次的工程桩试验全过程详实的数据,分析预应力管桩在桩基施工初步阶段,如何结合试验桩静载试验数据合理地选择桩端持力层。 Through the experience of the construction of prestressed pipe piles and the experience of pile foundations in the example projects, the detailed data of the whole process of two groups of test pile test and one batch of engineering pile test are used to analyze the prestressed pipe pile in the initial stage of pile foundation construction , How to choose the pile bearing layer reasonably based on the static load test data of the test pile.
