| Abstract: | In order to promote the development of immersed tunnel operation and maintenance technology, through literature research, field investigation and data mining, the technical achievements of immersed tunnel at home and abroad, operation and damage situation, detection and evaluation technology, disease prevention and treatment, and development prospect of operation and maintenance technology were systematically combed. Based on the key information such as the application of immersed tunnel, length of pipe section and buried depth, the development situation at home and abroad was explained. The operation status of immersed tunnel was briefly described, and the data mining analysis was focused on the common damage characteristics of immersed tunnel joints, main structure, subsidiary structure and facilities. The tunnel detection, monitoring and evaluation technologies were compared and analyzed, and the progress and shortcomings of current detection and evaluation technologies at home and abroad were expounded. From the perspectives of early prevention and late treatment, the common diseases such as uneven settlement, cracks and water leakage of immersed tunnel were described. Based on the operation and maintenance information of immersed tunnel, the development trend of its operation and maintenance technology was prospected. The results show that the immersed tunnel construction has achieved fruitful results, but there are many technical problems in operation and maintenance. In-service immersed tunnels have been damaged by excessive (differential) settlement, cracks and water leakage, and the uneven settlement of tube joints is the most common. The detection of immersed tunnel is still based on structural detection objects and traditional periodic detection methods. The evaluation and diagnosis of immersed tunnel mostly focus on the angle of settlement control standard, and the service performance evaluation considering multi-factor comprehensive angle is still blank. The common diseases of immersed tunnel should adhere to the countermeasures of prevention in construction period and treatment in operation period. In the future, the operation and maintenance of immersed tunnel will expand to all elements of operation environment, and pay more attention to new technologies such as real-time automatic monitoring technology, big data intelligent evaluation technology and state-based maintenance strategy. |
