| 摘 要： | 目前关于既有隧道改扩建的研究较少,大多凭借新建隧道的设计、施工经验进行改建.以福建省福州市二环路金鸡岭隧道扩建为依托,并结合隧道现状,拟定多个方案进行数值模拟比选,研究成果可为类似的隧道设计施工提供参考.

| Abstract: | As there is a few studies on existing tunnel expansion which have been carried out by design and con- struction experience of new-built tunnels, in this paper, being based on practice of Jingjilin Tunnel Expansion Project of the Second Ring-road of Fuzhou City of Fujian Province, combined with current situation of tunnels, numerical simulation comparison and selection for construction schemes have been implemented, the study achievements could provide references for similar tunnel design and construction. |
