摘　　要：为充分发挥装配式结构的工厂化、模具化、机械化、标准化优势,将装配化引入至矿山法隧道建设中。通过对国内外类似工程详细、深入的调研,借鉴国内外盾构、TBM的成熟设计和施工经验,综合工程类比、理论分析、数值模拟分析、试验研究与现场应用反馈等技术手段,开展地铁矿山法隧道装配式二次衬砌结构初步研究。结果认为矿山法隧道二次衬砌结构采用全部预制构件进行生产及安装可行。矿山法隧道装配式二次衬砌采用马蹄形断面形式,钢筋混凝土平板形衬砌片,衬砌片厚度为300 mm或350 mm,分6块,全部预制,错缝拼接,环宽1200 mm,衬砌片连接采用螺栓连接,根据拼装机设计原理(是否能够提供对衬砌片的持续纵向挤压力)的不同可采用弯螺栓或者直螺栓。Prefabricated structures have the advantages of factory,mold,mechanization,and standardization;it can be brought into a metro tunnel constructed by the mining method.Detailed and in-depth investigation of similar projects in China and abroad are conducted.As part of the investigation,a preliminary research on the prefabricated secondary lining structure of a metro tunnel constructed by the mining method is carried out using engineering analogy,theoretical analysis,numerical simulation analysis,experimental research,and field application feedback based on the mature design and construction experience of shield and TBM.The results show that it is feasible to use prefabricated components for the secondary lining structure of a tunnel constructed using the mining method.The prefabricated secondary lining adopts a horseshoe-shaped cross-section,reinforced concrete flat lining with a thickness of 300 mm or 350 mm and 6 blocks,and a staggered joint with ring width of 1200 mm.The lining sheets are connected by curved or straight bolts according to the design principle of erectors.
