摘要
为保证小净距隧道开挖过程中围岩的稳定,介绍施工中的开挖顺序、钻爆要求、中间岩体加固措施等关键技术,以及施工该类型隧道对监控量测工作的特殊要求,本工程顺利完工的实践可为同类工程提供参考。
To ensure the stability of the surrounding rock during tne excavation of the small-spaced tunnel,strict digging sequences, special requirements for drilling-blasting, and the solidification measures for the medium rock bodies, all of which are discussed in detail in this paper, have to be adopted. The paper also expounds the special requirements for monitoring and survey work. It may serve as a reference for similar projects.
