针对柔性桩的沉降问题 ,结合分层的剪切位移法和摄动法提出了一种新的计算柔性桩沉降可靠度的方法 ,并用该法研究了土的空间变异性对柔性桩沉降可靠性指标的影响 .指出采用简化的集中参数法计算柔性桩沉降的可靠性指标在某些情况下会得出不安全的结果
Aiming at the settlement of flexible piles, a new method to calculate the settlement reliability of flexible piles is proposed based on the layered shear displacement method and perturbation method. The method is used to study the influence of spatial variability of soil on the settlement reliability of flexible piles It is pointed out that the use of a simplified lumped parameter method to calculate the reliability index of flexible pile settlement can lead to unsafe results in some cases
