Chang Law Analysis of the Horizontal Displacement of the Arch Crest Dam Section of the Geheyan Concrete Gravity Arch Dam

Abstract:

Monitoring data of the arch crown dam section of the Geheyan concrete gravity arch dam were qualitatively and quantitatively analyzed. The analysis results show that the measured data and year changes of the dam horizontal displacement are small, the influence of the water level and temperature on the arch crown dam section is normal, the influence of the aging on the dam horizontal displacement is little, and the aging component has become stable. Therefore, it can be shown that the arch crown dam section of the Geheyan concrete gravity dam is in elastic state, and the horizontal displacement is accord with general deformation law of concrete arch dams.
