So according to the technology regulation of reclamation engineering, hydraulic calculation must be carried out in the design of final closure. this paper firstly introduces the progression and present situation of reclamation engineering, emphasizing on the features of present reclamation and on the experiences and theories of home and abroad ; using fortran perfects the hydraulic calculation program of the closure and makes the program to meet different conditions ( such as considering flood, the variation of time interval, multi - entrance, multi - reservoir capacity ), and after comparing and analyzing a great deal of schemes, the reasonable computation scheme was brought up ; the interface of the program was carried out by the programming language vb to make the process of calculation become easier and more distinct, so the result can be analyzed and handled more directly ; vb is used in the later management of the result to plot the graphic chart of the isoline of the maximum of hydraulic element ( the velocity of flow, the drop height and the rate of flow ) automatically ; finally it was applied in the reclamation project of dongbidao of fuqing

海工程的特點及在圍
海工程實踐中積累的經驗和理論;利用fortran語言完善堵口工程龍口水力計算程序,使程序可以滿足圍
海工程復雜工況下(如考慮內港洪水、計算時段的變化、多口門、多庫容、多水
閘)的龍口水力計算,並進行大量方案的比較和分析,提出合理計算方案;利用面向對象的可視化編程語言vb進行界面開發,使計算過程有良好的人機界面,更直觀地對計算結果進行分析和處理;計算結果的后處理採用vb編程實現龍口水力要素最大值等值線圖的繪制;並運用所編軟體對福建省福清市東壁島圍墾工程進行龍口水力計算,為堵口合龍提供科學依據。
Seawall and sluice are the parts constructed in advance, while final closure is the last part in construction. the hydraulic condition during the final closure process is worse than that during any other processes. and with the compressing of the entrance, the hydraulic condition becomes badly, the drop height of entrance can reach 2 to 3 meter, the maximum velocity of flow even reaches 6 to 8 meter per second and flow condition also becomes complex
海堤和水
閘的修建都是圍
海工程先期施工的部分,堵口則是
海堤修築的最後階段,堵口合龍成敗關繫到圍
海工程成敗,由於此階段所遇到的水力條件十分惡劣,口門落差可達2 3m ,流速最大可達到6 8m / s ,且水流極其復雜,根據我國《圍
海工程技術規范》規定圍
海堵口必須進行龍口水力計算。
