基于Matlab的展茅流域圩區防洪排澇分析

摘要: 基于Matlab 強大的數學計算功能與友好的界面, 針對舟山市普陀區展茅流域進行防洪排澇分析, 選擇最不利外海潮位和內河水位組合, 采用圩區排澇水文模擬法, 并利用Matlab 軟件所提供的三次樣條函數擬合、二元散亂點上的插值等工具編程實現了計算. 實例說明了該方法應用的有效性. 結果表明, 該方法計算過程簡單, 可供工程設計和施工參
考.

Abstract :At present , the concrete cutoff wall withlowelastic modulus is adoptedin main parts of impervious systemof hydraulic maintenance and strengthening engineering . However , due to the complex hydraulic conditions , the actual operating evaluation of concrete
cutoff wall withlowelastic modulus is currently a problem. The establishment of concrete cutoff wall adaptability evaluationsystemof low elastic modulus is talked about inthe paper based on hydraulic characteristics , as well as the cutoff wall internal characteristics and external conditions , whichis a scientific and comprehensive example of lowelastic concrete modulus applicative for the further study .
