摘　　要：本文提出利用COX模型转换数据的方式,应用最小二乘支持向量机模型,计算分析并预测大坝变形规律及趋势。由于在数据转换过程中,充分考虑了坝体监测点的分布特点,且模型输入数据为全部监测点的转换数据,因此,比起以往回归模型单就某一点的位移数据进行计算分析,本文提出的模型可以更好地在整体上得到大坝的活动变形规律。In this paper,the original data,conversed by the COX model,are substituted into the least squares support vector machine model for computational analysis and prediction of dam deformation law and trends.Since in the data conversion process,full account of the distribution of dam monitoring points,and the input data for the model conversion data of all monitoring points,thus,compared to the previous regression models alone displacement of a point to calculate the data analysis,the proposed model can get better overall activity in the dam deformation law.
