摘　　要：从调查中原地区城镇住宅楼面活荷载出发,阐述了建立持久性及临时性活荷载概率模型的过程。根据统计得到的房间单位面积的重量,按不同使用功能将房间分类,绘制各类房间荷载分布折线图,根据折线图形状呈左偏态的特点,假设统计荷载服从极值Ⅰ型分布,采用χ2检验法对假设的分布进行检验。结果表明,各种情况下均没有理由拒绝统计荷载服从极值Ⅰ型分布。给出了代表中原地区城镇住宅楼面持久性活荷载和临时性活荷载最大值的概率分布函数和统计参数,对编制荷载新规范具有参考价值。From the survey of the floor live load of the residential building in towns of the Central Plains region, the probability model of the durable live load and the temporary live load is given. According to the weight in unit area and the different using functions of each apartment, some classifications can be derived and then the load distributing polygonal line figure of each apartment can be drawn. Due to the polygonal line figure taking on left-deflection, statistic loads are hypothesized submiting to extreme Ⅰ -type distribution. These hypothetical distributions are tested with χ^2 . The analysis results show that the statistic load isn＇t rejected submiting to extreme Ⅰ-type distribution in each case. The probability distributing functions and statistical parameters of the maximum of the durable live load and the temporary live load are obtained. The results would be references in compiling the new specification.
