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。
運用抽樣統計方法計算施工洪水頻率時,隨機抽樣統計計算量巨大,在多覈微機上利用多線程併行計算能提高運算效率。在分析施工洪水抽樣統計模型和多線程計算可行性的基礎上,採用Delphi編製多線程的洪水頻率分析計算軟件。單線程和多線程計算效能分析比較說明:利用多線程計算在計算量較大的情況下,具有明顯的時間優勢。

In the flood frequency computation with the statistical sampling method, the computation work of random sam-pling 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 multithread flood frequency analysis code is developed with Delphi.Efficiency comparison shows that the multithread computation method is much superior when large amount of calculation is needed.
