摘要
为了解决海底隧道穿越软弱破碎地层所遇到的技术难题,文章针对海底隧道软弱破碎地层特点,从超前地质预报、注浆方案选择标准、注浆材料、注浆参数、注浆工艺以及注浆效果检验方面进行了分析总结,提出了钻爆法海底隧道软弱破碎地层注浆加固堵水技术和总体对策,并阐述了其在工程中的应用效果。
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 straturn. 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.
