摘要
以广西某水下钻孔爆破地震测试结果为依据,介绍产生地震波的原因,并通过采用美国SAULS公司产生的NC SC5000型测振仪进行测试,分析和总结了影响水下钻孔爆破地震效应的主要因素,并对公路桥的爆破振动安全判据提出建议。
Based on the test results of the underwater drilling and blasting vibration in Guangxi, this paper introduces the reason of generating vibration. Tested with the adoption of the vibration instrument NCSC5000 manufactured by American SAULS Co., the main factors influencing underwater drilling and blasting vibration effect are analyzed and summarized. Suggestions are raised in this paper regarding the safety criterion of blasting vibration to highway bridges.
