围垦堤 meaning in English
polder dyke
Examples
- Mathematical model is used to calculate and analyze water line in case of 9 kinds of flood flow levels respectively in reservoir . there are two programs including with enclose tideland for cultivation and without it in every flow level
利用数学模型分别对9个洪水流量级进行了水库沿程水面线计算分析，每个流量级分有围垦堤和没有围垦堤两个方案。 - Effecting of enclose tideland for cultivation on water level in the same flow level are quantitatively analyzed , the main achievement and suggestions are given as follows : ( 1 ) the water level rise is the most which effected by enclose tideland for cultivation dyke when flow is 2000m3 / s , the max water level difference in case of enclose tideland for cultivation dyke or no arrives 0 . 66 m
定量地分析了围垦堤对同级流量下的库水位的影响，主要成果结论及建议如下： ( 1 ) 2000m ~ 3 /时库区围垦堤对水库水位抬升最大，有无围垦堤水库水位差最大达到0 . 66m 。 - Qualitative analysis on the effect of flood control and engineering safety - , seizing lots of water conservancy effective adjust storage . then making water level risen and reservoir backwater enlarged in the same flow level ? effect on beach and the buildings across river , soil salinization caused by flow from a lower to a higher place and unsmooth groundwater drainage destroy of travel resource caused by disorder enclose tideland for cultivation in reservoir silt up flood plain are given , then presents enclose tideland for cultivation dyke is important cause which water level rise in reservoir
本文从青铜峡水库泥沙淤积入手，分析水库泥沙淤积特性和库区围垦堤开发利用淤积滩地的现状，对防洪安全及工程安全的影响、侵占大量的有效调蓄库容、造成同级流量下水库水位抬升水库回水上延、对沿岸及过河建筑构成影响、因水位抬升致使库区周边灌区地下水排水不畅乃至倒灌而造成土地盐碱化、对水库库区大量淤积滩地无序围垦造成旅游资源破坏等五方面影响的定性分析，提出库区围垦堤是水库水位抬升的重要原因。 - ( 2 ) the water level ascending value effected by enclose tideland for cultivation dyke is reverse proportion to flows below 2000m ' / s , water level has surpassed the top of dam when flow is above 2000m3 / s , water level ascending value is declassing in the same flow level caused by enclose tideland for cultivation dyke
( 2 ) 2000m ~ 3 s以时，围垦堤影响的水库水位抬高水位值随流量增大而增大差逐渐减少，在2000m ~ 3 s以上时，水位已经超过围垦堤堤顶，围垦堤所引起的同级流量下水位抬高值逐渐减少。
