摘    要:从目前爆破振动经验公式入手,指出其中参数的选取存在的问题.通过引入数理统计中可靠度的概念,对现场实测数据进行了回归分析,并讨论了公式中K值在一定置信区间下的选用,为爆破振动速度的估计提供了一个合理范围,克服了以往仅给出单一振动速度公式的不足.建立了适合于当地地质条件的振动速度计算公式,从而大大提高了计算精度,确保了爆破施工的安全,为以后的爆破施工提供了参考依据.

关 键 词:回归分析  可靠度  K值  振动速度

Abstract:The problem of the parameter selection in the present experiential vibration velocity formula was pointed out.Through introducing the reliability scope in symbolic statistics,the reasonable selection of value of K in certain confident interval on regression analysis was discussed on the basis of the testing data on site,and the reasonable scope for the estimation of the vibration velocity formula was provided,which overcame the deficiency in only giving the single vibration formula.The formula of calculating vibration velocity was established suitable for the local geology condition,which can sharply increase the calculation precision,ensure the safety of blasting construction and provide the reference for the future blasting.
Keywords:regression analysis  reliability scope  value of K  vibration velocity
