Current Situation and Outlook of Research into Subaqueous Shield Tunnel Construction and O&M Technologies
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 and maintenance systems.The key technologies for construction and O&M of subaqueous shield tunnel are comprehen-sively analyzed herein,in the hope of finding more reliable and efficient solutions for maintaining safety of subaqueous shield tunnel in its full life cycle.
