摘要
三峡工程临时船闸布置在升船机右侧，且相互平行，中间由中隔墩分开。当临时船闸侧岩石开挖高程接近６９ｍ时，升船机部位再从８８ｍ高程向下开挖。为了确保在爆破开挖过程中中隔墩的安全与稳定。在试验与研究的基础上，确定了爆破振速控制的安全判据。
The temporary shiplock is situated to the right of the shiplift and runs parallel to it.They are separated by a rock wall.When the rock excavation of the shiplock gets to elevation of 69m,the excavation of the shiplift begins from elevation of 88m.To ensure safety and steady of the rock wall during the period of blasting excavation,a safety criterion for controlling the blast vibration effect determined by experimental study is described in this paper.
