台风灾害对琼北地区城市建设的影响——以海口某不规则超高层建筑的数值模拟分析为例

通过数值模拟分析海口2栋超高层建筑的平均风压分布和空间风致响应.对比发现,不规则形体超高层建筑将会产生更大位移,在琼北地区应尽量避免建造超高层建筑.基于此,归纳总结琼北地区城市规划中的防风策略与手段,提出对防风规划的建议,以期对我国热带台风高发城市的规划方向有所预测.为琼北地区城市布局与新建筑在形体特征和高度上的确定提供依据.

Effects of Typhoon Disasters on Urban Constructions in Northern Area of Hainan -- in the Case of the Numerical Simulation Analysis of an Irregular High-rise Building in Haikou

This paper simulates the average wind pressure distributions and space wind-induced responses of two super high-rise buildings in Haikou.Results show that irregular shape super high-rise buildings will have a larger displacement,and the construction of super high-rise buildings with irregular shapes should be avoided in northern area in Hainan,which provides an important basis for urban layout and new construction determined on the physical characteristics and height.Based on this,we summarize strategies and means for defending typhoon in urban planning in the northern area of Hainan,put forward some proposals on defending typhoon,expecting some prediction on the urban planning in tropical city full of typhoon in China.
