Abstract: With the analysis of characteristics of subsea permeable channels, the pre-grouting and additional grouting in fracture grouting methods are successfully used to solve the problem of water off during tunnel construction. It has provided a guarantee for the construction safety, and proposed the principle, parameters, equipment, processes, materials and grouting effect of grouting methods for subsea cracks. The methods are also successfully applied to Jiaozhou bay subsea tunnel through the fracture zones. The results provide a reference for similar engineering.

Key words: subsea tunnel, permeable channel, fracture grouting, grouting parameters
