摘要

隧道开挖对邻近既有建（构）筑物桩基乃至整个建（构）筑物的稳定与安全带来不同程度的影响。采用大型通用有限元分析软件ABAQUS，结合工程算例，模拟隧道开挖对邻近桩基工作性能的影响。首先分析了当邻近桩基与隧道竖向轴线之间的水平距离和桩长变化时隧道开挖所引起的单桩反应变化规律；在此基础上，研究了隧道开挖对邻近群桩的影响，对比分析了群桩中基桩与单桩的工作性能差异，得出了一些对工程建设有意义的结论。

Abstract

Tunneling has certain influences on adjacent pile foundations

even on safety and stability of overall building. The large finite element analytical software ABAQUS is employed to simulate and analyze the influence on the working performance of adjacent pile foundation induced by tunneling based on an engineering example. Firstly the reaction and the change laws of single pile induced by the changes of horizontal distance between adjacent pile foundation and vertical axial line and the change of pile length are analyzed. Then

the responses of pile group induced by adjacent tunneling are studied

and some comparisons between pile group and single pile are made. Finally

some conclusions are drawn to offer the references to related engineering.
