武汉长江隧道工程施工技术

武汉长江公路隧道是在建采用盾构法穿越长江的隧道中第一条贯通的隧道，通过对盾构重难点分析研究，明确了施工重点控制环节。通过盾构始发、不同地层掘进、盾构到达施工实践，总结出在特定地层和高水压条件下采用泥水盾构修建隧道的施工技术及特殊情况下的技术措施，为泥水盾构施工积累了宝贵的经验.

Construction Technology for Yangtze River Crossing Tunnel in Wuhan, China

Yangtze River crossing tunnel in Wuhan, China is the first highway tunnel in China that has been constructed by shield method. The critical control points of the works are determined on basis of analysis on the critical and fundamental items of the works. The construction technology for tunnels constructed by slurry shields under particular ground conditions and high ground water pressures and the countermeasures for specific conditions are summarized on basis of the engineering practice of shield launching, shield boring in different ground conditions and shield arriving. Therefore, valuable experience is accumulated for the construction of slurry shields in the paper.
