Abstract EN
This paper presents research on the abutment forces of a double-curvature arch dam during overload based on numerical calculation results obtained through finite element method by Ansys.
Results show that, with an increase in elevation, the abutment forces and bending moment of the arch dam increase first and then decrease from the bottom to the top of the dam.
Abutment forces and bending moment reach their maximum at the middle or middle-down portion of the dam.
The distributions of abutment forces and moment do not change during overload.
The magnitude of each arch layer’s forces and moment increases linearly during overload.
This result indicates that each arch layer transmits bearing loads to the rocks of the left and right banks steadily.
This research explains the operating mechanism of an arch dam under normal and overload conditions.
It provides a simple method to calculate the distribution of forces F x and F y and a new method to calculate the overload factor of an arch dam through the estimation of arch layers based on the redistribution characteristic of arch abutment forces.
