【摘要】：在未來幾十年,鐵路、公路、水利水電、城市地鐵、海底隧道等大批不同類型的隧道需要建設(shè),而TBM將成為我國隧道工程首選的施工方法,它快速、安全、高效、環(huán)保等優(yōu)點(diǎn)必將推動(dòng)TBM的長(zhǎng)遠(yuǎn)發(fā)展。TBM掘進(jìn)性能研究和刀具磨損研究對(duì)TBM設(shè)計(jì)、施工和成本預(yù)算都是十分重要的,而且TBM在施工過程中要根據(jù)不同地質(zhì)條件來適當(dāng)調(diào)整刀盤推力、刀盤扭矩、刀盤轉(zhuǎn)速以及掘進(jìn)速度等主要參數(shù),才能使TBM安全、快速和高效的掘進(jìn)。本文以東北特長(zhǎng)隧道TBM工程為背景,進(jìn)行了大量TBM現(xiàn)場(chǎng)測(cè)試和數(shù)據(jù)記錄,包括地質(zhì)巖石取樣、掘進(jìn)數(shù)據(jù)記錄、刀具磨損記錄、刀具備件損耗及原因記錄等,對(duì)巖石物理力學(xué)性能進(jìn)行試驗(yàn),包括單軸抗壓強(qiáng)度試驗(yàn)和磨蝕性試驗(yàn)等,再利用分析軟件,對(duì)東北特長(zhǎng)隧道TBM工程TBM掘進(jìn)性能和刀具磨損進(jìn)行統(tǒng)計(jì)分析以及相關(guān)性分析和研究,包括TBM作業(yè)利用率和設(shè)備完好率的分析、TBM掘進(jìn)性能與掘進(jìn)參數(shù)相關(guān)性研究;刀具磨損量、換刀次數(shù)統(tǒng)計(jì)、刀具磨損與圍巖情況相關(guān)性分析等。本論文研究表明:TBM在不同圍巖情況下掘進(jìn)作業(yè)利用率有明顯差別,TBM貫入度和掘進(jìn)速度與某些掘進(jìn)參數(shù)(刀盤推力、刀盤轉(zhuǎn)速等)和地質(zhì)參數(shù)(單軸抗壓強(qiáng)度等)之間有較強(qiáng)的相關(guān)性;刀具在不同地質(zhì)條件下磨損量差異很大,不同類型刀具的磨損情況亦相差較大,并且磨損量有一定規(guī)律。本文研究結(jié)果和數(shù)據(jù)對(duì)其它TBM工程具有重要參考和借鑒價(jià)值。
[Abstract]:In the coming decades, a large number of different types of tunnels, such as railway, highway, water conservancy and hydropower, urban subway, undersea tunnel and so on, will need to be built, and TBM will become the preferred construction method for tunnel engineering in China, which is fast, safe and efficient. Environmental protection and other advantages will promote the long-term development of TBM. The study of tunneling performance and tool wear is very important to the design, construction and cost budget of TBM. Moreover, the thrust of cutter head should be adjusted according to different geological conditions in the construction process of TBM. The main parameters, such as the torque of the cutter head, the speed of the cutter head and the driving speed, can make the TBM drive safely, quickly and efficiently. In this paper, based on the TBM project of the northeast extra-long tunnel, a large number of TBM field tests and data records are carried out, including geological rock sampling, tunneling data recording, tool wear record, tool spare parts loss and cause record, etc. The physical and mechanical properties of rock are tested, including uniaxial compressive strength test and abrasion test, and the statistical analysis and correlation analysis of TBM tunneling performance and tool wear of TBM project in northeast extra-long tunnel are carried out by using analysis software. This paper includes the analysis of TBM operation utilization ratio and equipment integrity rate, the correlation study of TBM tunneling performance and tunneling parameters, tool wear quantity, tool changing times statistics, tool wear and surrounding rock condition correlation analysis, and so on. In this paper, it is shown that there are significant differences in the utilization ratio of tunneling operation between TBM and TBM under different surrounding rock conditions, and between TBM penetration and tunneling velocity and some tunneling parameters (thrust of cutter head). There is a strong correlation between the rotational speed of the cutter and the geological parameters (uniaxial compressive strength, etc.), the wear quantity of the cutting tool is very different under different geological conditions, and the wear condition of different types of cutting tools is also quite different, and the wear amount is regular. The results and data of this paper have important reference value for other TBM projects.
