鼓楼站施工对既有南北向道路隧道的影响分析

Analysis of Influence to Existing South-north Tunnel in Construction the Gulou Subway Station

接近施工是近年来城市建设中经常遇到的问题 ,南京地铁鼓楼站距南北向道路隧道的水平净间距为 14m ,鼓楼站为三层岛式车站 ,南北向道路隧道为双连拱结构 ,复合式衬砌。施工会引起南北向道路隧道向车站的位移 ,引起结构受力的变化 。

In recent yeas, city's development usually barges up against adjacent constructions. The Gulou station of Nanjing Subway uses three layers framework and island type platform, and double arch structure and compound lining are used in the south-north tunnel near the station. For the level distance between them is only 14 meters, the construction can make the tunnel move to the station and change it's suffering. So it's necessaryto adopt corresponding measures to guarantee the tunnel's safety and capacity of normal use for considering the influence. The paper analyzes the influence of the adjacent construction and introducesthe measures in construction.
