Analysis on dam heel crack and unsymmetrical deformation of concrete arch dam

After many studies and researches, some key technologies, such as the shape optimization of arch dam, crack and seepage control at dam heel, the seismic fortification measures, the flood discharging and energy dissipation measures, dam foundation treatment and the abutment foundation treatment, have been solved progressively.
