摘要
According to the characteristic of the road collapse data in mined-out area, a method based on empirical mode decomposition (EMD) and weighted least squares support vector machines (WLS-SVM) has been put forward to forecast the ground subsidence and applied into the coal-mining-induced collapse prediction of Changping high way in Jilin Province. Comparing the measured data in situ and the predicted data by WLS-SVM and BP neural network, the result shows that the suggested method has relatively high forecast accuracy and can be applied widely.
