摘要
中轻冰区往往因缺乏覆冰资料,难以进行覆冰频率统计。基于覆冰强度的概念,提出一种简单的覆冰重现期分析模型,试图解决历史覆冰重现期难以确定的问题,并认为在同一气候区内相邻地区间冰厚随高程的变率是相近的。据此,导出安徽沿江江南地区设计冰厚的经验关系,并进行合理性检验。
It is usually difficult to fulfill icing frequency statistics in medium-light icing area because of data shortage. Based on the concept of icing strength, a simple analyzing model of icing return period is put forward in the paper, and it is assumed that the change rates of ice thickness along with elevation are similar for adjacent areas in the same climate zone. On this basis, the empirical formula for design ice thickness of the southern area along the Yangtze River in Anhui province is deduced, and the rationality is also verified.
