Abstract: Based on the deformation of body and base of Dagangshan arch dam, the distribution characteristic as well as its development and change rule during initial impoundment is studied. Then its working behavior in storage period is analyzed. Monitoring results indicates that the deformation of body and base conforms to the general rule, and the numeric value stays in the designed control scope, which is worthy reference for other super-high arch dams.

Key words: Dagangshan arch dam, initial impoundment, analysis on deformation monitoring data
