Abstract:To ensure the stability of the surrounding rock during the 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.
Keywords:small-spaced tunnel  the solidification of the rock body  construction sequence  small lead tube slip-casting  pre-stressed anchoring rod  blast  monitor and survey
