摘要
以非线性回归法对爆破挤淤振动监测数据分别进行了萨道夫斯基公式及其修正公式的回归,得出拟合公式及参数。经过分析对比,认为采用萨道夫斯基修正公式可以较好地揭示爆破挤淤振动衰减规律,为爆破挤淤的理论参数设计以及振动安全控制提供了参考依据。
Both the Sadaosk formula and the modified Sadaosk formula were used to study the vibration attenuation from ground improvement with blasting technique. Nonlinear regression analysis was performed to obtain the parameters required in the formulae using monitoring data. The modified Sadaosk formula was found to fit the monitoring data better than the Sadaosk formula. Therefore, it is recommended that the modified Sadosk formula be used in the design of ground improvement with blasting technique and vibration control associated with the blasting technique.
