该文介绍了合肥至芜湖高等级公路试刀山右线隧穿越大型溶洞、断层、地层交接复合带及处理溶洞堆积物设计与施工的体会和经验.如:锁定相邻危险地段以巩固作业区“后方”;采用高压注浆和错杆加固洞周岩体堆积物;采用钢筋混凝土“管梁”整体穿越大岩溶区;采用“眼镜工法”变大跨为小跨,确保施工安全;严格控制围岩变形防止结构沉降等,可供类似隧道设计与施工参考.“,”The Shidaoshan Tunnel is a double-line tunnel on the Hefei-Wuhu high-grade highway with its right-line tunnel crossing big cavern, fault,joined stratum complex zone and having much accumula tions in the tunnel. The paper introduces the experiences and understandings of design and construc tion of this kind of tunnel and the treatment of the accumulations in following aspects,such as:locking up adjacent danger sections to ensure the rear-area of working region,strcngthening rock accumula tions around cavern by high-pressure grouting and using anchor bolts,crossing big karst region by ap plying reinforced concrete tube-beam as a whole, converting large span into small span by using “glasses construction method”to ensure the construction safety,controlling strictly the deformation of surrounding rock to prevent the subsidence of structure,etc. They are valuable as reference for design and construction of similar tunnels.
