摘要
本文介绍云南龙江水电站110m高混凝土双曲拱坝坝基开挖的施工方法。施工中主要从控制坝基预裂孔的孔距、孔深和线装药密度等几个方面进行研究，在现场实施中，取得了较好的开挖效果，确保了坝基开挖质量。
The construction method of 110m concrete dome arm foundation excavation is introduced in this paper. During the construction, the research on the control of pre-splitting hole pitch, depth and linear charge density of the dam foundation is carried out, and during the on-site implementation, a good excavation result is obtained, thereby guaranteeing the dam foundation excavation quality.
