摘　　要：以斜坡结构物二维冰力计算公式为理论依据,给出平原水库设计所需要的冰力学参数的合理取值。通过开展水库冬季冰面现场观测,得到冰层第二次爬坡发生时的等效应变速率、典型冰温;结合大量的冰力学性质的试验研究,给出在护坡工程中最不利条件下,即冰层第二次爬坡时水库冰弯曲强度、弹性模量及冰与护坡材料间动摩擦系数的设计取值。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.
