Stability Analysis of Left Abutment of the Arch Dam in Siduhe Hydropower Station

Chen Ji

Abstract

In the left abutment of the arch dam in Siduhe hydropower station,the geological condition is not satisfactory.Therefore,an adjustment is made in the dam axis to avoid the negative influence of the geological formations on stability of the arch abutment. Also,the arch dam of hybrid curve type is chosen,which fits the asymmetric terrain better when the dam axis moves upstream. Stability analysis of the dam abutment shows that it is stable.
