摘　　要：利用钦州市辖区19个气象观测站建站以来至2022年的风速资料,采用数理统计等方法推算重现期为50a的最大风速,研究分析基本风压值及其分布规律。结果表明,钦州市基本风速为11.7~40.4m·s^(-1),基本风压在0.08k~0.97kN·m^(-2)之间,二者总体上均呈沿海向内陆逐渐减小的分布特征。钦州国家基本气象站的基本风压计算值为0.51kN·m^(-2),与《建筑结构荷载规范》推荐值的差值最小,为0.04kN·m^(-2),可为当地提供更精细的基本风压参考。Using the wind speed data of 19 meteorological observation stations in Qinzhou City since the establishment of the station until 2022,the maximum wind speed with a 50-year return period was projected and then the value of the reference wind pressure was determined.The results show that the basic wind speeds at each station range from 11.7 m·s^(-1) to 40.4 m·s^(-1),and the reference wind pressures range from 0.08 kN·m^(-2) to 0.97 kN·m^(-2),both of which show a gradual decreasing distribution from the coast to the inland.The calculated value of the reference wind pressure at the Qinzhou National Meteorological Station is 0.51 kN·m^(-2),and the difference with the recommended value of the Load code for the design of building structures is the smallest,which is 0.04 kN·m^(-2),which can provide a finer reference of the reference wind pressure for the present Qinzhou area.
