| Abstract: | a formula for calculating bending moment acting on the dam slope caused by ice cover during lowering of pool level is established. In this formula the gravity of ice plate is regarded as distributed load and the restrain conditions between dam and ice cover as well as the characteristics of ice are taken into consideration. |
