Abstract: There is a strict restriction on the rising rate of reservoir level during the initial impoundment period of high earth-rock dams. Through analysis and research on the change of reservoir level and the dam deformation during the initial impoundment period, it is found that high rising rate of reservoir level is prone to cause large deformation, and in serious cases, it may damage the seepage prevention structure. Therefore, it is of significance to strictly control the rising process of reservoir level and strengthen the dam deformation monitoring in the initial impoundment period to ensure the dam safety.

Key words: earth-rock dam, core, deformation
