摘要
以温州赵山渡引水工程许岙隧洞进口开挖为例 ,阐述了土质围岩中隧洞口开挖采用减震爆破与插筋纵梁相结合的特殊施工方法。该法是目前国内隧洞掘进中的一项新工艺 ,为土质围岩中隧洞口的安全掘进提供了有益的经验 。
Through taking the excavation of opening section of Xu′ao tunnel in Zhaoshandu Diversion project, Wenzhou City, Zhejiang Province as an example, a special method of combining shock reducing blasting with advance bars is expounded for excavation of opening section of a tunnel in terrene surrounding rock At present, this method is a new technology for tunnel excavation at home, and has provided some profitable experience for safe excavation of opening section of a tunnel in terrene surrounding rock It will be an important reference for similar projects
