摘要

摘要: 深基坑的变形控制是设计中重要的一环，当深基坑邻近既有建（构）筑物时尤其重要。针对某深基坑与邻近地铁车站的相互影响分析，应用有限元建立岩土–结构整体计算模型，为减小基坑变形对地铁的影响，从安全可靠，经济合理的方面出发，提出针对措施及建议，供类似工程参考。

Abstract: Deformation control is an important ring in the design of deep excavations, and it is particularly important when there are adjacent buildings (structures). Based on a deep excavation adjacent to subway station, using finite element method, a model for soil-structure interaction is established. In order to reduce the influence of excavation deformation on the subway, the relevant measures and suggestions are put forward considering the safe, economic and reasonable characteristics. It may provide a reference for similar projects.
