摘要
隧洞开挖是输水隧洞施工中的一个关键环节,开挖质量控制关系到工程安全、施工成本。以湖南省椒花水库工程为例,分析了水工隧洞施工钻爆法开挖中频繁出现的超挖、欠挖问题,对主要影响因素进行了分析总结,并有针对性地提出了对策。
Excavation is one of the key links in the construction of water conveyance tunnel, quality control during excavation is closely related to the safety and cost of project construction. Taking the Jiaohua Reservoir in Hunan Province as an example, analysis is made on the problems of frequent over-excavation and under-excavation during the excavation of hydraulic tunnel by drilling and blasting method. The key influencing factors are evaluated and summarized with proposal of specific measures.
