“数理统计法”求解水库可利用调节水量的应用

The application of Mathematical statistics solving reservoir live storage capacity

对于无资料地区水库利用"数理统计法"进行多年调节计算时,会有大量试算过程,试算不当就会进入误区循环,浪费大量的经历。利用假定水库供水量算得调节系数α推求库容系数β多进行水库年调节计算,求出假定取水量条件下必备的兴利库容与设计兴利库容相比较,若误差大,则重新反复上述过程,直至无误。按上述步骤,利用计算机结合普列什柯夫线解图,可迅速查解水库可利用调节水量。

For the region of free information, regulation water amount of reservoir can be calculate by mathematical statistics, which has a large number of trial calculation, and inappropriate calculation will enter circulation and waste a lot of experience. In reservoir annual regulating calculation, the reservoir＇s storage capacity factor β is inquired by adjustable coefficient α got by assumed the amount of water supply, and get the live storage capacity, then compared with design live storage capacity, if the error bigger, the above process need to be repeated, until correct. According to the above steps, the use of computers combined with prieto Shike Fu--line solution map can quickly search available solution to adjust water reservoir.
