无量纲参数图表法应用于围海工程龙口流速的研究

Dimensional Parameter Graphology Method of the Flow Rate in the Closure Gap of Coast Reclamation Work

堵口程序设计决定整个围海工程的成败,目前国内多采用水力要素最大值等值线图法反映各项水力要素随口门尺寸的变化规律,并据此进行堵口顺序设计。因此,探讨利用一种新的图解法——无量纲参数图表法,不仅可从理论上选择合理的合龙顺序,而且在施工过程中能根据现场各因素变化随时很方便地调整堵口合龙施工顺序。

Reasonable closure program design is the key to the success of reclamation engineering. At present, the isopleth map of the maximum value of the hydraulic elements in China reflects changing rules of each hydraulic element with various blocking sizes, so as to design blocking program based on these rules. This article discusses how to apply a new graphic method dimensional parameter graphology to design the blocking program. Through choosing reasonably the blocking order, we can adjust the blocking eonstrucion order according to changing conditions at site at any time in the construction process.
