General Deformation

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.

The Stability

A new method that 3D numerical simulation combined with anti-cut stability analysis is employed to analyze the stability of Majiabian gravity dam, and the results of the analysis conform to the measured value. And this method can be used in analysis of congener gravity dam. When the results of 2D sliding stability analysis satisfy Code’s requirements, elastic material can be used in 3D numerical simulation. The results of water level sensitivity analysis and deformation modulus of its foundation sensitivity analysis indicates that this gravity dam is insensitive to water level; grouting method can be adopted to enhance its foundation. The results of abutment under tension stress analysis indicate that tension stress of abutment must be considered in high gravity dam design, and arch can be used for reducing the tension stress.
