南京地铁十号线长江隧道总体方案设计研究

Study on the Overall Scheme Design of the Yangtze River Tunnel of Nanjing Metro Line 10

根据南京地铁十号线过长江区间隧道的建设条件,对地铁十号线过江段总体方案设计中的几个难点问题及解决方案进行了研究与介绍,其中采用10.2m内径的单洞双线盾构隧道方案有效地解决了隧道通风防灾、疏散救援等难点问题,降低了工程建设风险和难度,该方案在国内地铁过江隧道中尚属首次采用,对类似工程有一定的借鉴作用。

According to the construction conditions of the tunnel across the Yangtze River of Nanjing Metro Line 10,this paper studies and introduces several difficult problems and solutions in the overall scheme design of the tunnel across the Yangtze River.The scheme of 10.2m inner diameter single tunnel double line shield tunnel effectively solves the difficulties of tunnel ventilation,disaster prevention,evacuation and rescue,and reduces the risk and difficulty of project construction.It is the first time that the scheme is used in the domestic subway tunnel crossing the river,which can be used for reference for similar projects.
