【摘要】：随着我国交通建设事业的不断的发展，公路隧道建设也逐渐发生着变化，其建设方式迫切需要向机械化施工模式转变。近年来随着对隧道机械化施工技术的深入研究，已开始推出了一些新设备和新工艺。在我国，机械化施工中的机械产品研发、技术理论创新、设备应用等方面还处于初级阶段，对隧道机械性能配置和新产品、新技术的研究并不深入。为促进新设备的使用、新工艺的研究和推广，提高隧道建设机械化水平，有必要对新设备的作业模式、隧道机械的性能配置和施工工艺进行深入研究。本论文针对这一问题，以国内某山岭公路隧道建设工程为试验对象，对以采用电脑凿岩台车和大型湿喷机组为基础的隧道机群施工作业模式、机群施工系统特性、机械性能配置等方面展开探索和研究。以目前常用的隧道新奥法施工技术和施工机械为基础，确定了公路隧道洞身开挖与支护机械化施工工艺过程。根据隧道设备选型原则和施工技术要求，对机械选型方法和影响因素进行了分析；结合隧道施工中常用主要机械的结构特点和使用性能，提出了以电脑凿岩台车和湿喷机为主要施工机械的单机施工作业模式。对隧道洞身开挖与支护机群施工系统进行划分，经分析得出存在包容制约关系的各施工子系统之间互相影响。通过对施工现场的数据统计分析，运用数理统计和随机服务理论对单机作业特性和机群施工系统工作特性进行研究，发现各单机作业特性分别符合特定的某种概率分布，并可以分析各机群施工子系统的运行状态。根据隧道洞身开挖与支护机群施工过程和机械化作业模式中的主要影响控制因素，建立了以施工系统运行状态、机械效率、进度、质量和成本作为评价机群作业模式指标的评价体系。通过对隧道洞身开挖与支护施工机群组成和机群施工配置原则的分析，得出了机群施工静态配置和动态配置方法，，静态配置主要是施工机械的初始配置，动态配置是用于指导隧道施工技术、环境条件发生变化时机械配置的动态调整。进而可以以机群配置方法来指导隧道机械化施工作业。
[Abstract]:With the continuous development of traffic construction in our country, highway tunnel construction is gradually changing, and its construction mode needs to be changed to mechanized construction mode urgently. In recent years, with the in-depth study of tunnel mechanized construction technology, Some new equipment and new processes have been introduced. In China, the research and development of mechanical products in mechanized construction, the innovation of technology theory, the application of equipment and so on are still in the initial stage. The research on the mechanical performance configuration and new products of tunnel is not deep in depth. In order to promote the use of new equipment, In order to improve the mechanization level of tunnel construction, it is necessary to study the operation mode of new equipment, the performance configuration of tunnel machinery and the construction technology. Aiming at this problem, taking a mountain highway tunnel construction project in China as the experimental object, this paper analyzes the construction mode of tunnel machinery group based on computer drilling platform and large wet jet unit, and the characteristics of the construction system of the tunnel cluster. Mechanical performance configuration and other aspects of exploration and research. Based on the construction technology and construction machinery commonly used at present, this paper determines the mechanized construction process of tunnel excavation and support, according to the principles of tunnel equipment selection and construction technology requirements. The methods and influencing factors of mechanical selection are analyzed, and the structural characteristics and performance of the main machinery commonly used in tunnel construction are analyzed. This paper puts forward a single machine construction mode, which takes computer drilling rig and wet jet machine as the main construction machinery. The construction system of tunnel excavation and support machinery group is divided. Through analysis, it is concluded that each construction subsystem with containment and restriction relationship affects each other. Based on the statistical analysis of the data of the construction site, the characteristics of the single machine and the construction system of the cluster are studied by using mathematical statistics and random service theory. It is found that the characteristics of the single machine accord with a certain probability distribution respectively. The operation state of construction subsystem of each cluster can be analyzed. According to the main control factors in the construction process of tunnel excavation and support machinery group and the mechanized operation mode, the operating state, mechanical efficiency and progress of the construction system are established. Quality and cost are the evaluation system for evaluating the operation mode of the cluster. Through the analysis of the composition of the construction machinery group and the construction configuration principle of the tunnel tunnel excavation and support, the static and dynamic configuration methods for the construction of the cluster are obtained. The static configuration is mainly the initial configuration of the construction machinery, the dynamic configuration is used to guide the tunnel construction technology, and the dynamic adjustment of the mechanical configuration can be used to guide the tunnel mechanized construction operation with the cluster configuration method.
