摘　　要：在我国经济飞速发展的当下,国家城镇化程度逐年加快,城市基础设施建设日趋完善,城市地道工程作为缓解交通压力分流车辆人流的有效手段被广泛建设使用。考虑到城市范围内人口密度较大,施工受限较多,选择合适的施工方式变得至关重要。针对呼和浩特市某地道工程实例,对其盖挖逆作法支护施工工艺进行概述和分析,得出盖挖逆作法支护施工工艺可以在高效完成工程作业的同时减小城市施工对市民生活的影响,有关经验可供相关专业人员参考。At the present of rapid economic development in China,the national urbanization has accelerated year by year and the construction of urban infrastructure is improving day by day.As an effective means of easing the traffic pressure and separating the vehicles and people,the urban subway engineering is widely adopted in the construction.By considering the high population density and more construction restrictions within a city,it is more important to select a suitable construction method.Aiming at the a subway engineering case in Hohhot City,its support construction technology of covered top-down excavation method is summarized and analyzed.The conclusion shows that the support construction technology of covered top-down excavation method can efficiently complete the engineering construction at the same time to decrease the influence of city construction on the life of citizens.The relative experience can be referred for the similar projects.
