摘要
随着城市地下空间的开发,盾构穿越已有河道的现象越来越普遍。如何合理地安排施工过程,确保河道上建筑物和施工安全尤为重要。以南京地铁四号线某区间盾构穿越秦淮河线路工程为例,总结克服施工过程中盾构隧道下穿河道和侧穿桥墩技术难题的经验,保证其安全、顺利地通过秦淮河河段。
With the development of urban underground space,the phenomena of shield tunnels crossing rivers is very comment. The critical issue for construction safety is how to arrange construction process. Based on the shield tunnel construction of Nanjing Metro Line No. 4 crossing the Qinhuai River,the solutions of river crossing and side crossing of bridge piers are fully discussed in order to ensure the safety of shield tunnel construction.
