flood curve
解釋
洪水曲線-
Firstly, the status of our nation ' s water resources, flood and arid hazards is overviewed to illustrate the necessity for study on dynamic control of flood season limited water level. disadvantages in traditional limitsd water level design, static control of limited water level design, static control of limited water level and fuzzy limited water level curve are pointed out, and mending methods for these are introduced. dynamic control and its key problems are analyzed hi next section. the allowable range of limited water level is determined, so as the allowable extreme risk index. the definition of extreme risk is re - illustrated, risk analysis methods in reservoir operation is discussed either. according to the definition of extreme risk rate, the allowable extreme risk rate of reservoir is systematically demonstrated with variant extreme risk indexes and flood season limited water level
本文首先闡述了我國水資源狀況和水旱災害、說明水庫汛期限制水位動態控制研究的必要性；介紹了傳統汛限水位設計、汛限水位靜態控制、模糊汛限水位過程線存在的問題及其初步改進方法；分析汛期限制水位動態控制的方法及關鍵問題；進一步闡述了水庫極限風險率的定義；根據極限風險率定義，詳細敘述了不同極限風險指標時、不同汛期限制水位下起調，水庫所能承受的極限風險率計算方法。然後，基於極限風險率計算方法，以白石水庫為背景，研究「考慮壩體自身安全、考慮壩體安全與下游防護對象控制下泄流量的汛限水位動態控制的極限風險率」 。 -

In order to test the grade criterions of flood disaster loss, logistic curve ( log ) model and genetic algorithm ( ga ) are used by the author who properly disposes the judge of disaster loss grade
為檢驗洪澇災情等級標準的合理性，筆者利用邏輯斯諦曲線和遺傳演算法對其加以驗證，並且在模型的級別判定上，做了適當的處理。 -
The research of reservoir design flood is one of basic works in this subject. it is based on the reasons, and the actual conditions of baipenzhu reservoir are combined, the following contents are researched in this paper : 1. according to the actual conditions of baipenzhu reservoir and through the compare of parameters estimation methods, a objective and having fine statistic characteristics p - iii frequency curve distribution parameters estimation method of proximate baipenzhu reservoir is putted
正是基於這種考慮，本論文結合白盆珠水庫的實際情況，本著理論性與實用性相結合的原則，重點研究以下內容： 1 、根據白盆珠水庫的實際情況，對各種參數估計方法進行比較，提出一種客觀、有良好統計特性、適用於白盆珠水庫的p ?型分佈參數估計方法； 2 、利用實測流量資料推求設計洪水過程； 3 、分析計算可能最大洪水（ pmf ） ； 4 、對兩種方法計算的設計洪水過程進行調洪演算，推求水庫特徵水位。 -
The further research in port engineering pile foundation is considered to be important of such as behavior and bearing capacity of laterally loaded single piles and pile groups, and the functional mode of wharf foundation pile under flood tide torrent, and load - deflection curve, and negative skin friction along the pile, et al. the bearing capacity and the negative skin friction of port engineering piles are analyzed, to satisfy port engineering development demand better
在港口樁基工程領域，港口工程水平承載（群）樁的工作性狀以及承載力計算方法，漲潮急流等動態荷載作用條件下碼頭基樁的受力性狀，樁的作用荷載與變位趨勢關系、樁的負摩擦等問題都要求作進一步的研究。本文致力於以港口工程樁基為主要研究對象，對港口工程（群）樁基水平承載力和負摩擦力進行研究，以更好地滿足港口工程建設需要。
