摘　　要：高速公路连拱隧道中隔墙是整个连拱隧道结构稳定的关键,是连拱隧道最重要的结构体,它对围岩的支撑稳定具有非常重要的作用。对连拱隧道中隔墙采用滑模连续浇筑施工技术进行总结分析,结合马草坡隧道实例主要研究了中隔墙滑模施工中的测量放线、滑模定位移动、混凝土浇筑及养护等。The middle partition wall in multi-arch tunnel of expressway is the key to the structural stability of the whole multi-arch tunnel and the most important structural body of the multi-arch tunnel. It plays a very important role in the stability of support of surrounding rocks. This paper summarizes and analyses the construction technology of continuous sliding mode pouring for the partition wall in multi-arch tunnel, and mainly studies the measurement and setting-out, sliding mode positioning and movement, concrete placing and maintenance in the construction of the partition wall sliding mode in combination with the example of Macaopo Tunnel.
