摘要
对临近城镇的某水电站坝基开挖爆破震动进行观测、分析和处理,得到了爆破地震波传播衰减经验公式。依据试验成果调整爆破设计与施工,严格控制起爆药量,合理采用相应的爆破降震措施,大大降低了爆破震动对爆区临近的建(构)筑物的影响,确保了该工程的爆破施工安全。对其他类似工程爆破具有参考价值。
The blasting vibration of dam foundation excavation at hydropower station near the town is observed, analyzed and processed. The decay experience formula of the blasting earthquake wave is obtained. According to the test results to adjust design and construction of blasting, exaction control detonation quantity, and the control measures of the blasting vibration are sensible to use. To reduce blasting vibration greatly for near building （structure）, and to ensure the blasting safe of the project. The successful experience can be referred by other similar projects.
