【摘要】：总结我国近30年来TBM设计与施工技术的发展历程,可归纳为以下5个阶段:1)研发探索和试用阶段;2)以国外施工承包商为主体,采用国外设计制造TBM施工我国隧道工程阶段;3)独立进行TBM招标采购和选型设计,并建立起自主的TBM施工队伍阶段;4)与国外厂家联合设计制造TBM,工程应用和自主施工快速发展阶段;5)实现TBM国产化,面向国内外TBM工程市场自主施工阶段。通过我国不同时期TBM施工的典型工程,介绍我国在复杂地质、大坡度、高海拔、不同直径、不同机型、超长隧洞TBM施工方面取得的经验、技术积累和业绩,展示我国TBM在穿越断层破碎带、软弱变形、岩爆、涌水等不良地质洞段取得的一系列施工新技术,以及最高月进尺1 868 m、平均月进尺超过600 m和掘进作业利用率超过40%的掘进技术水平。分析TBM在极硬岩、大断层破碎带、软弱大变形围岩、强岩爆围岩、涌水突泥洞段、高地热隧洞和超长隧洞工程中施工面临的风险和挑战,并提出一些相应的技术措施和对策,期望这些措施和对策在未来大量实际工程中进一步得到实践验证、优化和改进,不断积累和创新TBM设计与施工新技术。
[Abstract]:This paper summarizes the development course of TBM design and construction technology in China in the past 30 years, which can be summarized as follows: 1) R & D exploration and trial stage 2) taking foreign construction contractors as the main body. Adopting foreign design and manufacture TBM to construct our country tunnel project stage 3) to carry on the TBM bidding purchase and type selection design independently, The independent TBM construction team stage 4) is designed and manufactured jointly with foreign manufacturers, and the rapid development stage of engineering application and independent construction is 5) to realize the localization of TBM and to meet the independent construction stage of TBM engineering market at home and abroad. This paper introduces the experience, technical accumulation and achievement of TBM construction in complex geology, large slope, high altitude, different diameters, different models and super long tunnels in China through typical projects of TBM construction in different periods in China. This paper presents a series of new construction techniques obtained by TBM in passing through fault fracture zone, soft deformation, rock burst, water gushing and so on. And the tunneling technology level with the highest monthly advance of 1 868 m, the average monthly advance of more than 600 m and the utilization ratio of the tunneling operation exceeding 40%. This paper analyzes the risks and challenges faced by TBM in the construction of extreme hard rock, large fault fracture zone, soft and large deformation surrounding rock, strong rock burst surrounding rock, gushing water outburst mud tunnel section, high geothermal tunnel and super long tunnel engineering, and puts forward some corresponding technical measures and countermeasures. It is expected that these measures and countermeasures will be further verified, optimized and improved in a large number of practical projects in the future, and that new TBM design and construction technologies will be accumulated and innovated continuously.
