黑龙江省胜利水库冰盖生消规律

Freeze-up and Break-up of Ice Cover on the Shengli Reservoir, Heilongjiang Province

寒区水库冰盖的生成与消失,是一种极其普遍的自然现象。冰盖的运动,常常破坏水库的大坝护坡,损失巨大。本文依据胜利水库冰盖生成与消失的10年观测资料,提出了冰盖运动以及相互作用和桃形压力场分布的特征,阐述了冰的增厚和消失过程及冰盖活动规律,对胜利水库工程设计和防冰害提供科学依据。

The freeze-up and break-up of ice cover on the reservoir is a popular natural phenomenon in cold region. Movement of the ice cover can damage the slope protection of the dam, causing losses in economics. Based on calculating and analyzing to the data of a decade observation on the ice cover formation and break-up on the shengli Reservoir, Heilongjiang Province, auther points out the characteristics of the ice cover movement and the distribution of peach-like pattern pressure field, and states the process of the ice thickening and vanishing, as well as the regularity of the ice cover activity. It can provide the scientific basis for the Shengli Reservoir engineering design and its ice-hazard protection.
