冰压力冰压力ice pressure b ingyali冰压jJ(iee Pressure)冰对水工建筑物表面的作用力。冰压力可分为两种,水库表面结冰后,因气温上升冰层膨胀而产生的压力称为静冰压力;冰块流动时,流冰撞击建筑物而产生的压力称为动冰压力。一般认为冰压力是一种短暂荷载。对于较高的坝,冰压力在各种荷载中所占比重不大,特别当水库操作频繁或冬季水位长期较低时,常可不考虑冰压力。对于低坝、闸墩、进水塔、胸墙等结构,当冰层较厚或当垂直坝面的水库吹程不大时,冰压力往往成为比较重要的荷载,有时可能将建筑物挤裂。设计人员应根据具体情况,决定是否计入冰压力。对于不宜承受巨大冰压力的部位,如闸门、进水口等处,常需采取防冻、破冰等措施。 静冰压力的大小与开始升温时的气温、气温的上升率及冰厚、冰的热膨胀系数、冰的弹性模量、冰的强度和水库岸边的约束情况等有关。中国重力坝设计规范推荐采用表1中的数值。 表中单位面积静冰压力乘以冰厚即为每米坝长的表1静冰压力表┌─────┬───┬───┬─────┬───┬───┬───┬───┐│最低温度 │一40 │一35 │一30一一25│一25 │一20 │一15 │一10 ││ (℃) │ │ │ │ │ │ │ │├─────┼───┼───┼─────┼───┼───┼───┼───┤│气温上升率│2 .5 │2 .5 │2 .5 │2 .0 │2 .0 │2 .0 │20 ││ ‘℃/h) │ │ │ │ │ │ │ │├─────┼───┼───┼─────┼───┼───┼───┼───┤│静冰压力 │28一40│25一35│23一30 │20一28│15一22│13一18│12一14││(T/m“) │ │ │ │ │ │ │ │└─────┴───┴───┴─────┴───┴───┴───┴───┘ 静冰压力。 动冰压力的大小与建筑物暴露面积的大小和形 状、表面的粗糙度、冰厚、冰块流速、流冰的抗碎强 度等有关。中国重力坝设计规范规定:当冰的运动方 向垂直或接近于垂直铅直坝面(指运动方向与坝轴线 的交角为800一90’)时,作用于坝面的动冰压力为: 尸。d一Kov。d。俪厌(吨) 式中K。为系数,决定于流冰的抗碎强度R。值(当 R。一100吨/米2时,K。一4 .3;R。一50吨/米“时,K。=3.0;R。=30吨/米2时,K。=2.36);V。
