Analysis of ground motion measurement data under engineering blasting condition

To ensure that large precision instruments and equipment are in the best working condition, it is necessary to provide a suitable environment for them. At this time, there high requirement vibration of foundation at location. Measuring parameters, analyzing state, taking damping measures during construction process basis premise installation normal work. Combined with an application example, paper briefly introduces general situation project blasting, obtains basic characteristic parameters such as peak velocity ground motion time arrival blasting operation; Based on principle regression analysis, relationship between distance detonation centers charge weight obtained by fitting Sadovsky formula.
