基于低碳消费视角的京津冀雾霾治理

通过某双曲型塔柱大跨凸面悬挑结构刚性模型测压风洞试验，得到了结构在不同风向角下的风压系数，研究了该结构上部悬挑结构和下部塔柱形结构的体型系数分布规律。结果表明：上部结构的正压区主要集中在结构外沿以及空心处内沿部分，其余部分基本为负压区。下部结构内压为负，迎风侧外压体型系数较大，背风侧外压体型系数基本上为一个稳定的负值。

Study on Low Carbon Consumption Patterns Based Haze and Fog in the Beijing Tianjin Hebei Region

Based on a hyperbolic columnar structure with large span convex cantilever roof rigid pressure testing model wind tunnel test, wind pressure coefficients under different wind directions are obtained. Shape coefficients distribution of the cantilever structure and the columnar structure are studied. Results show that the positive pressures of upper structure are mainly focused on the outer edge and inner edge of the roof, the pressures on other areas are negative. The internal pressures of lower structure are negative, the external shape coefficients on windward are relatively high, the external shape coefficients on leeward are negative with little change.
