According to the theory of slope structures in two-dimensional formulas for calculation of ice force,the reasonable value of ice mechanics parameter in the design of the plain reservoir is given.Through the observation of winter ice field,the strain rate,the typical ice temperature are obtained when the ice appears second climbing;combining the experimental research on ice mechanical properties of large,ice bending strength,elastic modulus and ice and revetment material friction coefficient between the design value are given at the most adverse conditions in slope protection project when the second climbing.
