【摘要】 隧道施工信息化管理技术是隧道新奥法施工的一项重要内容,它既是隧道施工安全的保证,又是对隧道支护结构进行优化的重要手段。结合小金口双连拱隧道的建设,通过对Ⅱ类围岩1-1量测断面测试数据信息的处理统计分析,首次建立了双连拱隧道结构构件的力学模型;分析和探讨了隧道围岩变形与围岩类别、开挖方法、支护时机及支护参数之间的关系;初步建立了双连拱隧道施工信息化管理技术计算机系统,这个系统由信息采集、信息传输、信息处理和信息反馈4个子系统组成。这些研究成果对类似工程也将具有重大指导意义和实际应用价值。更多还原

【Abstract】 The informational management technique of the tunnel construction is an important content in the construction of the New Austrian Tunneling Method. According to the construction of the twin-arch tunnel of Xiaojinkou,by the statistical analysis of the measurement data of the section 1-1 in the class Ⅱ surrounding rock masses, the mechanical models of the structural members in the twin-arch tunnel are proposed, including the model of the contact stress between the surrounding rock masses and the first lining, the model of the axial force and bending moment of the steel framework, the model of the axial force of the anchorage bolt and the model of axial force and bending moment of the secondary lining. The relationships among the deformation of surrounding rock masses, the class of surrounding rock masses, excavation method, time of support and parameters of the support are put forward. The primary computer system of informational management of the construction of the twin-arch tunnel is set up. The system is composed of data collection, data transmission, data processing and data feeding-back. These research results are of guiding significance and practical application value for the similarly tunnel cases.更多还原
