摘　　要：上中路隧道是国内首条采用超大直径(14.87 m)盾构机施工掘进的双管双层隧道,在完成了第一条隧道掘进施工进洞后,采用了工作井内盾构机原地调头的方案进行第二条隧道的掘进施工。针对超大直径盾构机原地转场的方案,将其与常规的盾构机进洞后解体吊装、再拼装的方案进行技术经济分析对比,证明原地转场方案在技术和经济方面的优势。Shangzhong Road Tunnel is a double-channel double-layer tunnel firstly constructed by the over-large diameter(14.87 m) shield machine in China. After the completion of the first tunnel tunneling in,the scheme of turning about the shield machine in site within the working shaft is used to construct the second tunnel. Aiming at the scheme of transferring over-large diameter shield machine in site, the article analyzes and compares the technologies and economies of this shield machine and the conventional shield machine to be disassembled, hoisted and reassembled after coming in. The result proves the scheme of transferring in site has the superiority in the technology and economy.
