| 摘 要： | 地面大面积堆载超载常常使地基软弱土体产生侧向变形，从而挤压邻近桩基，因而对桩基上部的构筑物不利。将桩体等效成板桩，用梁单元模拟，以一现场试验为依据，章采用平面有限元分析了堆载超载影响下的相邻桩基性状。

| Abstract: | Piles which are referenced to passive piles may be of no use, frequently subjected to the soil movements due to surcharge loads inducing bending moments and deflections in the piles in many engineering practice cases, such as dock, bridge abutments, industry workshop. And this may lead to their superstructures distress or failure. So it is significant to study the behaviour of passive piles. In the paper, a geotechnical finite element analysis software package, named Plaxis 8.2, was used to perform the back analysis of an in-situ test of passive piles. Finite element method is also used to simulate the behaviour of piles which is subjected to the soil movements due to surcharge loads under the various influencing factors such as pile space, soil properties, and so on. |
