摘要

According to the structural character of earth dam of Feilaixia Multipurpose Project, this paper analyses the displacement regularity of the dam top of a typical dam section with the plane finite element method. Then the horizontal displacement of the dam top of combination of different water level has been obtained. According a binary quadratic regression the model of the relation between the horizontal displacement of the dam top and the water level has been based. On this basis analyzing the observation data of the horizontal displacement, considering the impact of temperature and time effects, taking into various adverse situation that can cause larger deformation of the dam body account, then the mixed model of horizontal displacement has been erected, and the concrete data of this dam section has also been studied out. These monitoring indexes of horizontal displacement can be consulted and provide important basis for monitoring the safe operation of the project.
