摘要
在萨道夫斯基公式因高差较大而难以反映爆区岩性的性质时,运用Matlab模糊系统工具箱建立峰值速度预测模型,并用测得数据对该模型进行了验证。验证结果表明:在样本数据较为完整的情况下,模型是可靠的。这为当传统方法不适用、特别是高差较为明显时的爆破震动预测提供了一种可供借鉴和参考的研究方法。
Sodev's empirical formula is difficult to reflect the characters of rock in forecasting blasting vibration because of large altitude difference.So this paper establishes a model for forecasting the peak velocity of blasting vibration with the fuzzy logic system toolbox in Matlab,and uses some test data to verify the model.The results show that the model is reliable when sample data is full.It provides a method for reference when traditional forecasting method is not applicable,especially the forecast of blasting vibration under large altitude difference.
