【摘要】：隨著我國(guó)交通建設(shè)事業(yè)的不斷的發(fā)展，公路隧道建設(shè)也逐漸發(fā)生著變化，其建設(shè)方式迫切需要向機(jī)械化施工模式轉(zhuǎn)變。近年來(lái)隨著對(duì)隧道機(jī)械化施工技術(shù)的深入研究，已開始推出了一些新設(shè)備和新工藝。 在我國(guó)，機(jī)械化施工中的機(jī)械產(chǎn)品研發(fā)、技術(shù)理論創(chuàng)新、設(shè)備應(yīng)用等方面還處于初級(jí)階段，對(duì)隧道機(jī)械性能配置和新產(chǎn)品、新技術(shù)的研究并不深入。為促進(jìn)新設(shè)備的使用、新工藝的研究和推廣，提高隧道建設(shè)機(jī)械化水平，有必要對(duì)新設(shè)備的作業(yè)模式、隧道機(jī)械的性能配置和施工工藝進(jìn)行深入研究。 本論文針對(duì)這一問題，以國(guó)內(nèi)某山嶺公路隧道建設(shè)工程為試驗(yàn)對(duì)象，對(duì)以采用電腦鑿巖臺(tái)車和大型濕噴機(jī)組為基礎(chǔ)的隧道機(jī)群施工作業(yè)模式、機(jī)群施工系統(tǒng)特性、機(jī)械性能配置等方面展開探索和研究。 以目前常用的隧道新奧法施工技術(shù)和施工機(jī)械為基礎(chǔ)，確定了公路隧道洞身開挖與支護(hù)機(jī)械化施工工藝過(guò)程。根據(jù)隧道設(shè)備選型原則和施工技術(shù)要求，對(duì)機(jī)械選型方法和影響因素進(jìn)行了分析；結(jié)合隧道施工中常用主要機(jī)械的結(jié)構(gòu)特點(diǎn)和使用性能，提出了以電腦鑿巖臺(tái)車和濕噴機(jī)為主要施工機(jī)械的單機(jī)施工作業(yè)模式。對(duì)隧道洞身開挖與支護(hù)機(jī)群施工系統(tǒng)進(jìn)行劃分，經(jīng)分析得出存在包容制約關(guān)系的各施工子系統(tǒng)之間互相影響。 通過(guò)對(duì)施工現(xiàn)場(chǎng)的數(shù)據(jù)統(tǒng)計(jì)分析，運(yùn)用數(shù)理統(tǒng)計(jì)和隨機(jī)服務(wù)理論對(duì)單機(jī)作業(yè)特性和機(jī)群施工系統(tǒng)工作特性進(jìn)行研究，發(fā)現(xiàn)各單機(jī)作業(yè)特性分別符合特定的某種概率分布，并可以分析各機(jī)群施工子系統(tǒng)的運(yùn)行狀態(tài)。 根據(jù)隧道洞身開挖與支護(hù)機(jī)群施工過(guò)程和機(jī)械化作業(yè)模式中的主要影響控制因素，建立了以施工系統(tǒng)運(yùn)行狀態(tài)、機(jī)械效率、進(jìn)度、質(zhì)量和成本作為評(píng)價(jià)機(jī)群作業(yè)模式指標(biāo)的評(píng)價(jià)體系。通過(guò)對(duì)隧道洞身開挖與支護(hù)施工機(jī)群組成和機(jī)群施工配置原則的分析，得出了機(jī)群施工靜態(tài)配置和動(dòng)態(tài)配置方法，，靜態(tài)配置主要是施工機(jī)械的初始配置，動(dòng)態(tài)配置是用于指導(dǎo)隧道施工技術(shù)、環(huán)境條件發(fā)生變化時(shí)機(jī)械配置的動(dòng)態(tài)調(diào)整。進(jìn)而可以以機(jī)群配置方法來(lái)指導(dǎo)隧道機(jī)械化施工作業(yè)。
[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.
