摘要
本文将冰盖板自重作为均布荷载 ,考虑了冰与坝坡冻结约束条件和冰的物理力学性质 ,建立了水位下降时 ,冰盖板对坝坡产生的破坏弯矩的计算公式 .与现有国内外同类公式相比 ,该公式物理意义明确 ,参数易于确定 ,符合工程实际 。
A formula for calculating bending moment acting on the dam slope caused by ice cover during lowering of pool level is established. In this formula the gravity of ice plate is regarded as distributed load and the restrain conditions between dam and ice cover as well as the characteristics of ice are taken into consideration.
