随着我国水下隧道建造技术的迅速发展,越来越多的长距离、大直径、高水压、复杂地质的水下盾构隧道将被修建,在建设过程中将面临更加复杂的地质条件和更为严格的技术标准。为保证水下盾构隧道的全寿命周期安全,文章阐述了水下盾构隧道的发展现状和所面临的挑战,并从水下隧道建造和运维两个角度对现有技术进行总结。建造方面分别从盾构机械优化和掘进参数控制技术、水下盾构隧道防水技术、水下盾构隧道的抗震设计3个角度进行了总结与展望:介绍了盾构掘进控制的发展现状,分析了盾构隧道修建引起渗水的原因以及现有防水技术,阐述了现阶段盾构隧道的抗震设计方法;运维方面分别从水下盾构隧道的耐久性长期监测技术、水下盾构隧道结构无损检测技术、水下盾构隧道智能运维系统3个角度进行了总结与展望:采用耐久性传感器的优化设计实现了对结构耐久性的长期监测;介绍了隧道结构的检测技术,包括衬砌表观质量检测技术和结构隐蔽病害检测技术,以及基于建设的智能运维系统如何实现对隧道的安全管理和运营高效监测。通过全面梳理水下盾构隧道建造和运维关键技术,以期为水下盾构隧道全寿命周期安全提供更加可靠和高效的解决方案。
With rapid development of subaqueous tunnel construction technologies of China,more and more sub⁃aqueous shield tunnels with long distance,large diameter,high hydraulic pressure and complex geological condi⁃tions will be built,and construction of such tunnels will be confronted with more complex geological conditions and more stringent technical standards.To ensure safety of subaqueous shield tunnels in their full life cycle,this paper expounds the current development of subaqueous shield tunnels and the challenges in their development,and offers a review of the existing technologies from the two aspects including construction and O&M of subaqueous tunnels.In terms of construction,this paper offers a review and outlook from 3 perspectives including shield machine optimi⁃zation and tunnelling parameters control technology,subaqueous shield tunnel waterproofing technology and sub⁃aqueous shield tunnel seismic design.The current development of shield tunnelling control technology is presented,the causes of water seepage in construction of shield tunnel and the existing waterproofing technologies are analyzed,and the currently available seismic design methods for shield tunnel are explained.In terms of O&M,this paper offers a review and outlook from 3 perspectives including technology for long-term durability monitoring of subaqueous shield tunnel,structural nondestructive testing technology for subaqueous shield tunnel and intelligent operation and maintenance system for subaqueous shield tunnel.Long-term monitoring of structural durability is realized by using durability sensors.The tunnel structure testing technologies are explained,including the lining apparent quality testing technology and concealed structural defect testing technology,and the approaches to achieving safety manage⁃ment and efficient monitoring of operation of tunnels are explained by analyzing the completed intelligent operation andmaintenancesystems.The key technologies for construction andO&M of subaqueous shield tunnel are comprehensively analyzed herein,in the hope of finding more reliable and efficient solutions for maintaining safety of subaqueous shield tunnel in its full life cycle.
