摘　　要：我国高寒地区水库,冬季封冻,冰盖层对大坝护坡作用复杂;接近尾冬时,气温回升,冰盖层膨胀可能会对护坡造成严重破坏。通过对红旗泡水库开挖的破冰槽的观测,对破冰槽两侧的固定测量点位移进行了分析,说明破冰槽可以减弱冰层膨胀对护坡的作用。Reservoirs always freeze in winter in the cold regions of China. And the action of the ice layer on the slope protection is complicated. When the winter is drawing to a close, the temperature rises. The expansion of the ice layer may cause serious damage to the slope protection. After observing the ice-breaking groove in the Hongqi-pao Reservior, we analyse the displacements of measuring points at the either side of the ice-breaking groove and illustrate that the ice-breaking groove can weaken the action of the ice layer on the slope protection.
