| 摘 要： | 云峰大坝抗滑墩基础开挖工程紧邻大坝,施工中采取了控制爆破技术,即小孔径、逐排分段爆破的开挖方式。不论是中部浅孔爆破,还是大坝近区岩体开挖,其振动观测结果总体合理。振动速度测值显示,爆破施工对大坝及帷幕的振动影响均处于安全允许范围以内,能够满足设计及相关规程规范的要求。

| Abstract: | Controlled blasting technology that is an excavation mode of small-bore and subordinate blasting row by row is used in construction.The observation result of vibration is rational either in middle shallow blasting or in rock excavation near the dam.The observation value of vibration velocity shows that influence of blasting construction on dam and curtain vibration is safe and could meet the demand of design and related regulations. |
