In the paper, river and the downstream area of dike are regarded as a whole system, and hydraulic model of coupling 1 - d river and gradual dike - break is established, therein the preissmann implicit difference scheme is applied to main river, and the fvm ( finite volume method ) is applied to the breach and polder
本文將河道與堤壩下游區域視為一個整體，對于單一河道採用preissmann四點隱式差分格式計算，對于潰口及圩區採用有限體積法，建立了一維河道與堤壩漸潰耦聯的水力模型，也是一維、二維耦合的水流模型。 -
( 4 ) the dike breach risk of the south bank is relative higher in wandering reaches. ( 5 ) the dike breach risk of the north bank is higher than the south bank in winding reaches. simultaneously, the evaluation results manifest that the evaluation indexes system established from the locomotion of incoming water and sediment load, the regional crustal stability, the evolvement of river regime and the stability of river dikes, can reflect the actual situation of hang river in the lower yellow river more fully
評價結果同時表明，從水沙運動、區域地殼穩定性、河勢演變和堤防穩定性4個方面建立評價指標體系，能夠更加全面的反映黃河下游懸河的實際情況;運用多層次模糊綜合評判法能夠較好地解決影響因素眾多、作用機制復雜的懸河決溢風險問題;運用gis技術強大的空間分析功能，使黃河下游懸河不同空間位置的決溢風險得到了量化，可以客觀地反映黃河下遊河道不同空間位置決溢風險的差別，對于指導防洪和河道治理的實踐具有重要的現實意義。 -
Based on analysis of hang river ' s actuality in the lower yellow river and researches related with evaluation of dike breach risk, it is put forward that the influencing factors of hang river dike beach risk in the lower yellow river should involve 4 aspects, the locomotion of incoming water and sediment load, the regional crustal stability, the evolvement of river regime and the stability of river dikes. the evaluation indexes system of hang river dike breach risk and uniform synthetic model are established from the 4 aspects. with the support of gis technology, the evaluation indexes system and the model of multi - hierarchical fuzzy synthetic judgment are applied to estimating the dike beach risk of hang river in the lower yellow river under different flood conditions
在對黃河下游懸河現狀、決溢風險評價有關研究進行分析的基礎上，本文提出黃河下游懸河決溢風險的影響因素應當包含水沙運動、區域地殼穩定性、河勢演變和堤防穩定性4個方面，並從這4個方面建立了黃河下游懸河決溢風險評價的指標體系和統一的綜合評價模型;在gis技術的支持下，運用評價指標體系和多層次模糊綜合評判模型，對不同洪水情景下黃河下游懸河的決溢風險狀況進行了評價。 -
Though the flood control engineering system improved the flood control standard and reduce the frequency of flood inundation and enlarger the protected area, but at the same time, the risk of dike broken and dam failed were added. moreover, people found that human living environment become worsen increasingly and the river ecosystem was destroyed
然而，在與洪水斗爭的過程中，人們發現雖然通過大規模的水利工程建設，提高了江河的防洪標準，減少了洪水泛濫的幾率，擴大了防洪保護的范圍，但同時也增加堤防、大壩潰決等的風險，而且人類發現生存環境日益惡化，河流生態系統被破壞等諸多問題。 -
This paper studies the ground motion of a triangular hill and antiplane response of a dike with flexible soil - structure interface while impacted by sh waves. the methods of complex function and moving coordinate system as well as a simple model are used here
通過復變函數法和移動坐標法，分別求解了sh波入射時三角形凸起地形對地震動的影響和柔性基礎上三角形壩體結構的出平面反應。 -
Based on hydrogeology and engineering geology reconnaissance, this problem constructs groundwater power field and system of chemistry characteristic through comprehensive analysis and research. monitoring groundwater table and water quality by means of choosing representative dike section, the paper appraises and forecasts that the influence to groundwater surroundings by building impermeable wall is or not unhealthy include the lever and the scope
本課題的特色是在水文、工程地質勘察基礎上，經一個水文年長期水位監測，經綜合分析研究后，建立地下水動力場和化學特徵系統，通過選擇代表性堤段對防滲墻建造前後地下水位和水質進行監測，評價和預測防滲墻建設對地下水環境是否存在不良影響以及影響的程度和范圍。 -
The whole system is a computer system for flood disaster mitigation decision and flood risk management which includes basic information management, flood risk calculation caused by dike broken, flood risk map making, flood risk information
系統是一個包括基礎信息管理、堤防潰決洪水風險計算、堤防潰決洪水風險圖、堤防潰決洪水風險查詢、堤防潰決洪水災害損失評估、區域防洪減災對策等模塊的為防洪減災輔助決策和洪災風險管理服務的計算機系統。
