Abstract: Combined with the engineering practice of the second subsea tunnel in Xiamen (Haicang Subsea Tunnel), this paper systematically studies and applies the application of comprehensive advanced geological prediction technology in the construction of similar high risk subsea tunnels, design blasting vibration reduction technology, prevent and deal with emergencies such as mud inrush and water inrush. It alsosummarizes a set suitable for the sea land junction under complex environmental conditions. Comprehensive technology for tunnel construction under urban trunk road, close to buildings, port area, large cross section of seabed, difficult construction organization and high risk, so as to provide technical guarantee for safe construction of the project.

Keywords:tunnels; subsea tunnel; drilling and blasting method; safety control; construction
