In this paper, the basic principle of using mathematical statistic analysis method to build mixed monitoring model of displacement of concrete dams is summarized, and the temperature factor and aging factor in the model are extended. Based on the observation data of a wide-gap gravity dam in Northeast China, the basic process of establishing a hybrid monitoring model is introduced in detail. The calculation results show that the hybrid monitoring model has higher fitting accuracy and can meet the engineering requirements.
