摘要
双线盾构隧道横向联络通道是灾情发生时重要的疏散和救援通道,建设需求在逐渐增加,其作为设计与施工时的重难点及风险点,施工中应当引起足够重视。基于此,文章针对国内外盾构隧道横向联络通道典型工程案例展开调研分析,将不同案例间的关键技术归纳总结为施工工法、主体结构开口型式、地层加固方案、主洞特殊环管片类型及主洞临时支撑型式五个方面,并展开了详细论述。
The cross passage in a double-track shield tunnel is an important evacuation and rescue passage in case of a disaster and its construction demand is gradually increasing.As an important,difficult and risky point in design and construction,enough attention should be paid to it in the process of construction.So,in this paper,the investigation and analysis were carried out for typical engineering cases of cross passages in shield tunnels at home and abroad and key technologies in different cases were summarized into five aspects:construction method,opening type of main structure,stratum reinforcement scheme,special segment ring type of main tunnel and temporary support type of main tunnel,which were then discussed in detail.
