| 摘 要： | 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。

| Abstract: | Based on the layered shear displacement method and perturbation method, a new method to calculate the settlement reliability index of a flexible pile is present. Using this method, the effect of a spatially varying soil medium on the settlement reliability index of a flexible pile is studied, and the concentrated parameter method is found to be unsafe in some case when it is used to calculate the settlement reliability index of a flexible pile. |
