摘 要: | 针对建筑结构抗震设计采用爆破振动加速度、工程爆破安全控制标准采用振动速度的不一致问题,通过理论分析和现场测试试验对爆破振动速度峰值和加速度峰值的等效换算及影响因素进行了分析。研究表明:爆破振动速度峰值和加速度峰值可通过公式进行等效换算,换算系数与最大单段药量、爆心距、起爆方式等影响因素相关。

Research on the Equivalent Conversion of Blasting Vibration Velocity and Acceleration |

Abstract: | [ ABSTRACT] For the inconsistency problem of adopting blasting vibration acceleration for the building structures seis ̄mic design and vibration velocity in the safety control standard of blasting, the equivalent conversion and the influence fac ̄tors of blasting vibration peak velocity and acceleration were studied by theoretical analysis and field test. Results show that a equivalent conversion between blasting vibration peak velocity and acceleration peak can be achieved by the formula. The conversion factor associates with the maximum explosive charge, absolute distance, detonation and other related factors. |
