Abstract：
In order to ensure the safety of subsea tunnel construction in a soft fractured stratum, advanced geological forecasting was performed and the selection standard of grouting schemes, grouting material, grouting parameters, grouting technology, and a grouting effect test were analyzed and summarized in light of the characteristics of this stratum. This paper discusses the general scheme of grouting reinforcement and water-stoping technique for mined subsea tunnels in weak, broken strata and describes its applications in the Qingdao Jiaozhou Bay and Xiamen Xiang'an subsea tunnels.
