摘　　要：随着城市化建设的进一步推进,城市地铁建设缓解了城市交通,促进了各城区之间的经济交流,持续满足城市的需求,但随之而来的环境问题也日益严重。本文以已建的成都地铁7号线某站点为例,基于FEFLOW的三维水流数值模拟,探讨3号线建成后、7号线还未建成;3、7号线建成后、10号线还未建成;3、7、10号线均已建成;长期运营情况等不同工况下地下空间开发利用情况及地下水综合响应,以及地下空间开发对地下水的扰动情况,从而为未来的地下空间开发提供理论支撑。With the further advancement of urbanization,urban subway construction has alleviated the urban traffic,promoted the economic exchanges among the urban areas,and continuously met the demands of the city.However,the consequent environmental problems have become increasingly serious.This paper takes a station of Chengdu metro line 7 as an example,and based on the three-dimensional flow numerical simulation of FEFLOW,discusses the construction of line 3 and line 7 after the completion of line 3.After the completion of line 7,line 10 has not yet been completed;Lines 3,7 and 10 have been completed.The development and utilization of underground space and the comprehensive response of groundwater under different working conditions such as long-term operation.And the disturbance of groundwater caused by the development of underground space.Thus provides the theoretical support for the future underground space development.
