摘　　要：运用抽样统计方法计算施工洪水频率时,随机抽样统计计算量巨大,在多核微机上利用多线程并行计算能提高运算效率。在分析施工洪水抽样统计模型和多线程计算可行性的基础上,采用Delphi编制多线程的洪水频率分析计算软件。单线程和多线程计算效能分析比较说明:利用多线程计算在计算量较大的情况下,具有明显的时间优势。In the flood frequency computation with the statistical sampling method, the computation work of random sampling statistics is dramatic. While the multithread parallel computation on multi-core microcomputer shows much higher efficiency. Thus, with an analysis on the statistical sampling model of flood frequency in construction period and the fea- sibility of multithread computation, a muhithread flood frequency analysis code is developed with Delphi. Efficiency comparison shows that the muhithread computation method is much superior when large amount of calculation is needed.
