摘　　要：土石坝变形统计模型是以大坝原观变形监测资料为基础,应用数学方法建立的一种用来描述监测点部位变形规律的数学模型,并以此预测和评价坝体的运行状态,从而达到对坝体结构安全进行监控的目的,对大坝安全管理具有非常积极的意义。文章采用统计回归方法,针对NZD心墙堆石坝的坝顶变形建立了HST统计模型,结果表明,HST能较好地拟合坝顶顺河向位移,可以采用HST模型对坝顶顺河向位移进行监控,以保证NZD心墙堆石坝运行安全。The deformation statistical model of earth and rock dams is a mathematical model established based on the original deformation monitoring data of the dam and using mathematical methods to describe the deformation laws of monitoring points.By predicting and evaluating the operational status of the dam body,the purpose of monitoring the structural safety of the dam body can be achieved,which has a very positive significance for dam safety management.This article uses statistical regression method to establish an HST statistical model for the deformation of the dam crest of NZD core wall rockfill dam.The results show that HST can fit the displacement of the dam crest along the river well,and the HST model can be used to monitor the displacement of the dam crest along the river to ensure the safe operation of NZD core wall rockfill dam.
