摘要
利用相关工程经验结合岩滩水电站地下洞室围岩的特点,进行了岩锚梁岩台开挖爆破试验。从现场爆破效果以及测量分析可以看出,两组爆破试验均取得了良好的效果,同时爆破振动速度满足设计和相关规范的要求,为后续岩台的开挖提供了重要的设计参数。
The blasting experiment on excavation of rock anchor beam rock bench was made,using relevant engineering experience in combination with surrounding rock characteristics of underground caves and chambers of Yantan hydropower station.From the site blasting effect and measurement analysis,we can see that both groups of blasting experiments have achieved good effects,and at the same time the blasting vibration speed also satisfes design requirements and related specifications,and important design parameters are provided for the excavation of downstream rock bench.
