Abstract

本发明公开了一种高耐久性叠合式盾构隧道管片结构及其设计方法，结构包括：外侧混凝土层、中间混凝土层、内侧混凝土层、第一螺栓孔、第二螺栓孔、钢筋笼、注浆孔；外侧混凝土层、中间混凝土层、内侧混凝土层依次叠合浇筑，且外侧混凝土层浇筑于中间混凝土层外侧；第一螺栓孔设置于中间混凝土层内，且其布置方向与隧道的纵向方向一致；第一螺栓孔用于连接沿隧道的纵向方向相邻的管片；第二螺栓孔一端贯穿内侧混凝土层，另一端贯穿管片结构的侧面；第二螺栓孔用于连接沿管片结构的环向相邻的管片；钢筋笼设置于管片结构内；注浆孔沿管片高度方向设置，贯穿整个管片结构。该管片结构具有结构性能安全可靠、施工方便、造价合理的优点。
