| 摘 要： | 复合载体夯扩预应力管桩是一种新型的载体桩。它采用PHC预应力管桩作为桩身,既可提高桩身的承载力,又易于保证桩身质量。目前,此类桩型在工程中应用得还比较少,缺乏相关的技术和经验,故对其设计和施工中的一些问题进行了研究与探讨,并提出了一些工程中可能出现的问题的见解。

| Abstract: | The ram-compaction pre-stressed pipe piles with composite bearing base are a new kind of ram-compaction piles with bearing base.The adoption of PHC pre-stressed pipe piles as the body can not only improve pile body strength,but also guarantee body quality.Currently,such piles in the engineering application is still relatively less and lack relevant skills and experience,so the problems of design and construction were studied and discussed,and a number of engineering problems that may arise were proposed. |
