摘　　要：综述了用数理统计分析方法建立混凝土坝位移混合监控模型的基本原理 ,并对模型中的温度因子和时效因子进行扩充。结合东北地区某宽缝重力坝原型观测资料 ,详细介绍了建立混合监控模型的基本过程。计算结果表明 ,混合监控模型的拟合精度较高 ,可以满足工程要求。This paper summarizes the fundamental principles of development of hybrid models of displacement for concrete dams by mathematic statistics method, and expands the temperature component and time effect component. A slotted gravity dam is taken as an example to introduce the procedure of the establishment of a hybrid model in detail. It has been proved that the fitting between the results of the hybrid model and the values observed in situ is accurate, and the forecasting of the displacement is reliable.
