摘　　要：针对高校图书馆的活荷载进行调查统计与分析,检验现行规范规定的图书馆楼面活荷载设计值是否安全可靠.由于该调查的实际操作难度较大,所以主要以宁夏大学图书馆为例来进行调查.对其活荷载进行调查分析,采用平稳二项随机过程确立其概率模型及其参数,再对其进行检验,检验方法有χ2检验和KS检验,可得到活荷载均服从极值Ⅰ型分布.经统计分析,建议采用5.0 kN/m2作为活荷载标准值进行结构设计仍然可靠,同时采用综合考虑时的活荷载标准值来进行结构设计是可行的.Inorder to test safe and reliable of live load designing value in current regulations hbrary floor, the live load of current libraries in universities was investigated and analyzed. Due to predictable difficulties in practice, the libraries in Ningxia University were taken for instance to investigate live loads of libraries. Its probability model was established and analyzed through stable binomial random process to and relative parameters. The model needs to be verified through X2 test or K-S test. The live load obeys type Ⅰ extreme value distribution. 5.0 kN/m^2 is recommended live load standard value, design is reliable. Meanwhile, it is feasible to adopt comprehensive consideration live load standard for structure designing, etc.
