地铁项目车站主体结构与附属结构交汇处围护结构拆除工艺研究

地铁施工中,车站附属结构通常在车站主体结构后施工,附属结构与车站交界处存在原有主体围护结构,为打通附属结构与主体结构,交汇处主体围护结构需要拆除。根据附属结构的受力要求,部分车站附属结构设计支撑对撑到交汇处主体围护结构、附属支撑以及交汇处主体围护结构的拆除存在高风险,对车站主体结构与附属结构交汇处围护结构拆除工艺进行研究是必要的。

Research on the Demolition Process of the Enclosure Structure at the Intersection of the Main Structure and the Subsidiary Structure of the Subway Project Station

In subway construction,the subsidiary structure of the station is usually constructed after the main structure of the station.The original main enclosure structure exists at the intersection of the subsidiary structure and the station.In order to get through the subsidiary structure and the main structure,the main enclosure at the intersection needs to be dismantled.According to the stress requirements of the subsidiary structure,the design support of some subsidiary structure of the station is of high risk to the dismantling of the main support structure,subsidiary support and the main enclosure structure at the intersection,so it is necessary to study the demolition process of the enclosure structure at the intersection of the main structure and the subsidiary structure of the station.
