摘要
介绍了向家坝水电站二期下游横向土石围堰拆除工程的爆破方案、参数选择、爆破网络及安全防护措施,防渗墙因上游堆石料挖除,增大了爆破飞石质量安全控制难度,通过爆破方案的严格实施,确保了爆破施工质量与安全。
The blasting program, parameter selection, blasting network and security measures of the cutoff wall demolition pro- ject of downstream transverse earth-rock cofferdam in the second-stage project in Xiangjiaba ttydropower Station are intro- duced. The quality and safety control difficulty of fly-rock from cutoff wall blasting was increased on account of the excavation of roekfill materials upstream. We ensured the quality and safety of the blasting construction by means of the strict implementa- tion of the blasting program.
