鸭河口火电厂取水口围堰拆除爆破与振动观测

Cofferdam demolition blasting and vibration monitoring for Yahekou Thermal Power Station

根据鸭河口火电厂供水工程的地形和施工条件,对施工围堰的拆除制订了详细的爆破方案,采用了控制单响药量、增加分段,微差起爆等减少爆破振动影响技术措施,并对爆破过程进行了监测和分析,结果表明,爆破效果达到了设计要求,爆破方案的设计是合理的。

On the basis of the topography and construction conditions of Yahekou Thermal Power Station Water Supply Engineering, a detail blasting plan was prepared for construction cofferdam demolition, and the blasting process is monitored and analyzed. The blasting effect indicated that the blasting plan is reasonable.
