为着力攻克滇中引水工程面临的"十大世界级技术难题",解决影响地下工程安全高效建设的卡脖子问题,在调研与科研攻关的基础上总结分析,分别从过活动断裂带、突涌水(泥)灾害、TBM超长距离掘进、软岩大变形等重点问题出发,探讨其致灾机制及研究进展,总结理论指导规律和现场施工技术突破.研究发现,相关地下工程难题的处理需重点解决灾害地质判别和精细调控等相关问题的研究,如已在滇中引水工程中进行应用的超前地质预报技术体系和"震源先导传感+洞内波场测量"的观测方式、TBM隧洞围岩类别现场快速判别辅助软件等;重点突破在于揭示灾变孕育机制,并形成高效掘进良性循环,如研发的三维应力作用下断层蠕滑错动相似模拟试验装置、TBM破岩过程中的主要掘进参数优化及同步衬砌相关工艺的探索等;重点掌握关于灾害控制及相关灾害预警方面的研究,如滇中红层软岩隧洞支护体适用性研究、滇中引水活动断裂隧洞段应力-应变综合监测预警平台构建等.此外,归纳了各项难题所面临的挑战并进行展望,为今后滇中引水工程研究难点及发展方向提供参考.
Research progress on key technologies for safe construction and efficient operation of the Dianzhong water diversion project-underground engineering
In order to overcome the"ten world-class technical problems"faced by the Central Yunnan Water Diversion Project and to solve the choking problem that affects the safe and efficient construction of underground projects,this paper discusses the disaster causing mechanism and summarizes research progress from the key issues of passing through the active fracture zone,water(mud)inrush disaster,TBM ultra long distance tunneling,and large deformation of soft rock,and further presents the theoretical guidance rules and breakthroughs in on-site construction technology.It is found that the treatment of relevant underground engineering problems needs to focus on the study of disaster geological discrimination and fine regulation,such as the advanced geological prediction technology system that has been applied in the Central Yunnan Water Diversion Project,the observation mode of"source pilot sensing+wave field measurement in the tunnel",and the auxiliary software for on-site rapid discrimination of TBM tunnel surrounding rock types.The key breakthrough lies in revealing the mechanism of disaster incubation and forming an efficient excavation virtuous cycle,such as the development of a 3D stress induced fault creep and dislocation simulation test device,optimization of main excavation parameters during TBM rock breaking process,and exploration of synchronous lining related technologies.Focus on mastering research on disaster control and related disaster warning,such as the applicability of support structures for red bed soft rock tunnels in central Yunnan,and the construction of a comprehensive stress-strain monitoring and warning platform for active fault tunnels in central Yunnan.In addition,the challenges faced by various difficulties are summarized and prospected to provide reference for the future research difficulties and development direction of Central Yunnan Water Diversion Project.
