LS-SVM analysis model and its application for prediction residential house's damage against blasting vibration from open pit mining
Abstract：Based on the LS-SVM theory,raised its application for prediction residential house's damage against blasting vibration of open pit mining.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.With the engineering practice test data for the training sample,built the LS-SVM forecasting model of residential house's damage against blasting vibration of open pit mining.A LS-SVM model was obtained through training 32 measured data of blasting vibration.The re-substitution method was introduced to verify the stability of LS-SVM model(false rate was 0)and was used to discriminate 12 new samples,test results was good.The results show that the ratio of mis-discrimination is lower,and the prediction results are identical with actual results.The LS-SVM model has good classifying performance,high predicted accuracy and can be used in practical blast engineering.
