| 摘 要： | 以瀑布沟水电站工程尾水隧洞和引水隧洞为例,探索利用弹性波检测技术分析和判断水电站尾水隧洞的围岩松动圈,研究根据弹性波检测数据评价水电站引水隧洞固结灌浆加固的质量与效果。结果表明,弹性波检测技术可为水工隧洞围岩支护和灌浆加固设计提供依据,也可为加固施工对隧洞围岩的完整性、连续性的提高所起的作用与效果提供有效验证。

Application of the Elastic Wave Detection Technology in Hydraulic Tunnel Construction |
| |
| Abstract: | Blasting excavation construction may cause loose circle in surrounding rock of hydraulic tunnels, which must be reinforced by lining and grouting.Thus, the elastic wave detection technology is applied in Pubugou Hydropower Sta-tion to estimate the loose circle that may appeared in the tailrace tunnel and also to evaluate the quality and effect of con-solidation grouting reinforcement in surrounding rock of the diversion tunnel.Results show that the elastic wave detection technique could be of great use for the design and evaluation of lining and grouting reinforcement of hydraulic tunnels. |
