中文摘要:
      介绍了机械连接竹节桩结构构造特点、机械连接方式及桩身与承台的连接方式。对比分析机械连接竹节桩和普通预应力管桩的抗压和抗拔承载力,通过现场的静载荷试验所得的荷载-沉降曲线,可以看出机械连接竹节桩的抗压和抗拔承载力相较于普通预应力管桩均有提高,其中抗拔承载力提高更为明显。对比同种桩型不同桩长的竹节桩的抗拔承载力,分析桩长对于抗拔承载力的影响。
英文摘要:
      Structural characteristics and mechanical connection of mechanical-connection bamboo joint piles and the connecting way of pile body and pile caps areintroduced.To compare the compressive bearing capacity and tensile bearing capacity of mechanical-connection bamboo joint piles and traditional prestressed pipe piles, the static loading tests are carried out. Load-settlement curves obtained from the static loading tests show that both compressive bearing capacity and tensile bearing capacity of mechanical-connection bamboo joint piles are enhanced, especially the tensile bearing capacity. Comparing mechanical-connection bamboo joint piles in different pile lengths, the effect of pile length on tensile bearing capacity of mechanical-connection bamboo joint piles were analyzed.
