摘要 针对单一模型在大坝变形预测中精度不高的问题,提出一种基于LS-SVM—马尔科夫模型的预测方法,即基于LS-SVM模型的预测结果,利用马尔科夫模型对其进行误差修正,从而提高了预测精度。通过对某拱坝变形的预测分析,并与LS-SVM模型预测结果进行对比,发现LS-SVM—马尔科夫模型的预测结果较符合实际情况,该模型具有更高的预测精度和优越性。 Aiming at the low precision of single model for dam deformation prediction, this paper proposes a predic tion method based on LS-SVM-Markov model. Namely, on the basis of LS-SVM model, Markov model is used to correct its error and ultimately it improves the accuracy of prediction. By analyzing an arch dam deformation prediction and comparing with LS-SVM model, it shows that the predicted result with LS-SVM-Markov model is more in line with the actual situation and the proposed model has higher predictive accuracy and superiority.
