【摘要】 冰对构造物的破坏,越来越引起人们的关注。如何确定作用于结构上的冰荷载,已成为工程设计中必须考虑的安全因素,规范法、公式法是冰荷载常用的计算方法。对国内外有关冰荷载计算公式的优缺点进行了分析与评价,提出对于D/h≤6的窄结构,使用多系数公式计算冰荷载是比较合理的,而前苏联规范比较适合宽尺度直立结构物的冰荷载计算;通过实验验证分析认为,在我国,按照规范进行计算,还是比较符合实际的。更多还原

【Abstract】 The structure damage which caused by the ice has increasingly drawn people’s attention and how to determine the ice load which acts on the structures has become the first considered safe factor in the engineering design.The methods of using norms and formulas are the common calculation methods.In this paper,the merits and demerits about the calculation methods of ice load at home and abroad were analyzed and evaluated,it deems that to the narrow structure of D/h≤6,using multi-factor formula to calculate the ice load is more reasonable,the Soviet Union norms more adapt to the ice load calculation problems of wide-scale vertical structures.Through the experimental verification and analysis,we find that the calculation which is in accordance with norms is quite in line with the reality.更多还原
