软土地基超长桩工程性状分析

Research on over-length pile behavior in soft soil foundations

通过沿海某大型火电厂主厂房地基中超长钻孔灌注桩静载试验和桩身轴力测试,探讨软土地基中超长钻孔灌注桩的承载力性状和荷载传递机理。超长桩桩身轴力的传递规律和侧阻力的发挥性状对软土地基中超长桩的理论研究和工程应用具有重要的参考价值。

According to the static loading test and the axial force test, the bearing capacity and load transfer mechanism of the over-length pile in the littoral soft clay are discussed. The transferring law of the axial force and the action of lateral friction resistance of the over-length pile in soft clay are important to the theoretical research and engineering application.
