保障社会交通条件下地下车站施工组织

Construction Organization of Underground Stations for Ensuring Social Traffic

摘要:

地下车站建设是地下轨道交通网建设、运营的关键环节。如何根据工程实际情况合理组织地下车站施工，在保障社会交通前提下顺利实施地下车站主体建设具有现实意义。以福州市轨道交通4号线凤凰池站、金牛山站工程为例，通过对项目施工难点分析及工艺比选，选择采取半盖挖顺作法。介绍了不同盖板设置形式下地下车站主体施工技术、施工场地布置及交通组织。该工程在保障社会交通的前提下顺利地实施了地下车站主体建设，可为后期相似工程提供借鉴。

Abstract:

The construction of underground stations is a key link in the construction and operation of underground rail transit network. How to reasonably organize the construction of underground station according to the practical conditions of the project, it is practically significant to smoothly implement the main construction of underground station under the premise of ensuring the social traffic. Taking the projects of Fenghuangchi Station and Jinniushan Station in Fuzhou Metro Line 4 at the examples, the construction difficulties and technologies of the project are analyzed and compared. Finally, the half-covered excavation sequential method is selected. The main construction technology, the construction site layout and traffic organization of the underground station with the different cover plates are introduced. The main construction of underground station of the project is smoothly implemented under the premise of ensuring the social traffic, which can provide the reference for the similar projects in the future.
