根据黄河口海区低盐度海冰和黄河冰的冰强度经验公式、冰盖传热量计算公式,分析了几种设计冰厚与设计气温对冰强度的影响。给出了设计气温取-15℃时冰强度与设计冰厚关系的经验公式,给出了设计冰厚分别取0.4m和0.7m时冰强度与设计气温关系的经验公式。计算出的冰强度若干结果及建议值可供胜利油田滨海结构物设计参考使用。
According to the ice strength empirical formula of the low salinity sea ice and the Yellow River ice in the Yellow River estuary, the heat transfer formula of the ice cap is analyzed, and the influence of several design ice thickness and designed air temperature on the ice strength is analyzed. The empirical formula of relationship between ice strength and design ice thickness at -15 ℃ is given, and the empirical formula of the relationship between ice strength and designed air temperature when design ice thickness is 0.4m and 0.7m respectively is given. Some calculated results and suggested values of ice strength are available for reference to design of coastal structures in Shengli Oilfield.
