【摘要】 考虑到目前的超长桩的桩侧荷载传递性状研究,基本上还是基于短桩理论,提出了考虑超长单桩桩侧摩阻力的深度效应的单桩荷载传递函数,并且将荷载传递法和有限元方法结合起来,采用该荷载传递函数来模拟单桩的桩侧荷载传递规律。用反演方法得出了该荷载传递函数的参数。算例表明:考虑深度效应的计算结果比不考虑深度效应的计算结果稍偏大,且与实测值更为接近,其结果更为合理。更多还原

【Abstract】 Considering that there is little study about shaft resistance transfer behavior of overlength pile and the theory is based on short pile yet,shaft load transfer function of overlength single pile which considering depth influence is presented.Moreover,load transfer method and FEM are combined.The load transfer function mentioned above is used to simulate rule of shaft resistance of single pile.Method of inversion is used to obtain parameters of shaft load transfer function.Example shows that the results that depth effect is considered is greater than the one that depth effect is not considered and the first one is closer to the test result.Considering depth effect is reasonable and necessary.更多还原
