摘要：

Saturated hyperbaric intervention technology has the advantages of high efficiency and security, but it also has many risks. Based on the Nanjing Weisan Road river-crossing tunnel project, the technological process of saturated hyperbaric intervention is introduced in detail, and the risks concerning geology, unstable pressure on the tunnel face, physical effects and equipment failure are analyzed, with corresponding countermeasures given. The practices show that these risks in the process of saturated hyperbaric intervention are controllable and suitable solutions can be made according to various existing risks and engineering features. ©, 2015, Editorial Office of Modern Tunnelling Technology".
