| 摘 要： | 为确保爆破引起的振动不会对临近新浇砼产生不利影响,通过对新浇砼跟踪监测以及对爆破振动衰减规律的测试分析,找到了爆破振动控制方法.然后,针对临近新浇砼因地制宜地采取了控制单响药量、调整孔网参数、实施预裂爆破等有效的爆破控制方法,确保新浇砼爆破振动的安全性,从而保证工程施工质量.

| Abstract: | In order to insure the safety of freshly-placing concrete under action of the blasting vibration, blasting vibration control measures were taken after monitoring of freshly-placing concrete and the analysis of the law of vibration attenuation was performed. The quality of the project was under good control. |
