摘　　要：随着我国城市建设的迅速发展,公铁隧道合建方案逐渐成为高效利用地下空间资源的行之有效的途径。文章基于武汉三阳路越江隧道工程条件,从对规划和用地的影响、施工难度、施工组织等多方面进行了综合比较分析,推荐采用六车道公铁合建隧道方案,并对盾构隧道横断面布置、隧道结构等进行了计算分析;针对超大直径盾构越江隧道建设所遇到的装备制造、长距离掘进、小净距施工及近距离侧穿建筑物等技术难点进行了可行性论证。With the rapid development of urban construction, the construction of rail-and-road combined tunnels is getting to be an effective way to realize efficient utilization of underground space. Based on the construction conditions of the Sanyang river-crossing tunnel in Wuhan, this paper proposes a construction scheme for the rail- and-road combined tunnel with six lanes based on a comprehensive comparison and analysis of the influences of urban planning and land use, construction difficulties, and construction organization. It describes the relevant calculations and analyses regarding the cross-section arrangement and tunnel structure, etc. Additionally, it discusses a feasibility study of technical difficulties such as equipment manufacturing, long-distance driving, constructing with a small clearance, and adjacent construction, and ultimately provides guidance for this project and similar ones in the future.
