Study on Deformation Mechanism and Influencing Factors of Arch Dam During Dam Impoundment

The deformation of arch dam during impoundment is critical to evaluate the safety dam, which influenced by many factors that have different action mechanisms. After monitoring data at stages were comprehensively analyzed, a finite element simulation analysis model can consider real temperature, stress and was set up with help method based on whole process effectively separate single caused water pressure, dead weight, creep, air seepage valley deformation. Then, mechanism gotten weight each influencing factor accurately defined, thus providing experience reference for law similar projects.
