根据实际水库观测冰盖与护坡的冻结情况，在实验室内进行模拟水库冰盖与护坡局部断面的冻结试验．采用冰与混凝土板间的冻结，进行一次冻结、多次冻结、冰晶冻结、雪冰冻结等模式．分析出冰压力与冻结力的关系；在不同温度下测得各种冻结情况中的冻结强度，给出冻结强度随着温度变化的规律和数值．其结果为寒区平原水库坝坡抵抗冰推力破坏提供了设计参数．
According to the freezing status of the observed ice sheets and the revetments in the actual reservoirs, a freezing experiment was conducted in the laboratory to simulate the partial section of the ice sheets and the slope protection of the reservoir. The use of ice and concrete between the frozen plate, a freeze, frozen repeatedly, frozen ice, frozen ice snow and other modes. The relationship between ice pressure and freezing force was analyzed. The freezing strength in various freezing conditions was measured at different temperatures, and the regularity and numerical value of freezing strength with temperature were given. The results provide the design parameters for the dam slope in cold area to resist the ice thrust damage.
