露天采矿爆破振动对民房危害预测的DDA模型及应用
Distance discriminant analysis model and its application for prediction residential house's damage against blasting vibration of open pit mining
摘要
Abstract
Due to the uncertain factors in blasting seismic effect of the control and evaluation, the distance discriminating analysis model for prediction of residential house's damage against blasting vibration of open pit mining was established based on the principles of Mahalanobis' distance discriminating analysis (DDA). Ten indexes, i.e., blasting vibration amplitude, dominant frequency, dominant frequency duration, gray joints intensity, the rate of brick walls, height of housing, roof forms, the structural column of circle beam, the quality of construction and site conditions, were used as blasting vibration prediction of residential house's damage discriminating factors. A DDA model was obtained through training 36 measured data of blasting vibration. The re-substitution method was introduced to verify the stability of DDA model and the DDA model was used to discriminate 12 new samples. The results show that the ratio of mis-discrimination is 2.78％, and the prediction results are identical with actual results. The DDA model has good classifying performance, high predicted accuracy and can be used in practical blast engineering.关键词
