地铁车站暗挖下穿大型人防地下商场的加固措施研究

伴随着我国城市地下轨道交通工程的迅速发展，越来越多的地铁工程侧穿和下穿既有地下建（构）筑物的问题涌现，处理这类问题的措施就变得复杂，尤其下穿变得更加麻烦。当地下车站上方的建（构）筑物无法拆除时，车站下穿则变得更为困难。以某地铁车站暗挖法下穿地下人防商场工程为例，介绍了暗挖车站下穿上方既有建筑物的设计重难点，探讨了该下穿工程的设计及施工处理对策，解决了此类工程的设计问题。

Study on Reinforcement Measure for Metro Station below Large Civil Air Defense Underground Stores

With the rapid development of urban underground rail transit construction projects in China, there is a problem that more and more metro projects passes side and below existing underground structures, measures for dealing with such problems have become more complicated, in particular, undercrossing becomes even more troublesome. When the buildings above the underground station cannot be removed, it is more difficult to construct the underground station. Based on the underground station below civil air defense store project with undercutting method, this paper describes the major design difficulties in construction of underground metro station below existing structures,and discussed and construction treatment strategies.
