In this thesis hydraulic experimental studies and theoretical analyses on the vortex - flow drop shaft were conduced and the following results were accomplished : ( 1 ) in the model test some hydraulic characteristics including the shape of air core in the center of the drop shaft, the radial distribution of water flow velocity and the distribution of pressure on the wall of the drop shaft were measured under the condition of high water head above 250m and large discharge above 1400m3 / s. ( 2 ) a kind of computational method for the spiral water flow in the air core region of drop shaft was discussed and applied and the results agree the experimental data well. ( 3 ) the total ratio of energy dissipation in the drop shaft can reach 90 % and the energy dissipation in every region was discussed quantitatively
本文通過試驗研究與理論分析對旋流式豎井泄洪洞應用於高水頭、大泄流量情況時存在的一些水力學問題進行了研究和探討，取得以下主要成果：一、結合小灣工程導流洞改建，對高水頭（ 252m ） 、大泄流量（ 1400m ~ 3 s ）條件下旋流式豎井中的水流運動特徵進行了比較全面的測量，包括空腔形態、徑向流速分佈及井壁壓強等；二、提出了豎井空腔段螺旋水流水力計算方法，其計算結果與實測值吻合良好；三、利用試驗與計算結果，對旋流式豎井的消能機理進行了探討，對豎井各部分的消能能力有了總體認識；四、對豎井下部消力井的合理井深進行了優化試驗研究，發現消力井合理深度為0 . 9d左右；五、通過試驗研究，歸納出豎井水流總摻氣量估算方法，為導流洞排氣方案的設計提供了參考依據；六、在高水頭、大流量條件下，豎井空腔段下部流速很高，盡管水流螺旋運動引起的離心力可以確保井壁壓強保持正壓，但空化數依然較低，因此豎井的空化空蝕始終是工程界關注的重大問題。The villagers built banks of earth to hold back the floodwaters
譯文：村民們築起土壩，防止洪水泛濫。Abstract : monthly rainfall data from 1951 to 1995 for june, july and august in 13 meteorological stations of the north china were used for accounting z index and discussing serious flood and drought featureas in these months. serious flood mainly happened in july and august, and sevious drought mainly happened in august. there were more flood in 1950 ' s to 1960 ' s and more drought since 1970 ' s in the north china. meanwhile, the deeper trough which covered the regions from the ural mts. to the balkhash lake play an important role in serious rainstom in rainy season in the north china. there often happened serious flood ( drought ) when the northwester pacific subtropical high was by west and north ( east and south ), and the sea surface temperature in the equatorial central and eastern pacific was mainly in dropping ( raising ) stage
文摘:利用華北平原地區的13個站點， 45年（ 1951 1995 ）的降水資料，對夏季4個時段（ 6月、 7月、 8月、 6 8月）進行了z指數計算，確定了該地區各個時段的嚴重澇年和嚴重旱年.發現華北地區雨季的嚴重洪澇主要集中在7 ， 8月，嚴重乾旱則主要發生在8月，並可明顯看出由50 60年代的多水期向70年代中期以後的少水期的轉變，另外，烏拉爾山到巴爾喀什湖附近的低壓槽加深和西北太平洋副熱帶高壓的北抬，對華北地區雨季持續性暴雨的產生起著決定性的作用.嚴重洪澇年的夏季（ 6 8月） ，西北太平洋副熱帶高壓偏西、偏北，赤道東太平洋海溫多處于下降階段;嚴重乾旱年西北太平洋副高偏東、偏南，赤道東太平洋海溫則處于上升階段It is difficult to be settled by classical theories because of fixed quality and quantity. this thesis bases on the improvement of traditional way, overcomes its i ack experience, takes the more advanced fuzzy decision - making and optimal selection theory, researches into the established model and gets the result that it ' s best to set pangtoupao storage and detention flood area on the left side of menjiang river by comparing the four schemes and ten objectives of fixed quality and quantity. the result holds identical views with the result of usual economic evaluation. so it ' s the first time using fuzzy decision - making and optimal selection theory to resolve the important and pragmatic problem comprehensively and scientifically
本文在總結用傳統的方法研究經驗與不足的基礎上，採用目前較先進的模糊優化理論及建立起的模型進行蓄滯洪區設置及規模研究，通過對嫩江四個蓄滯洪區方案， 10個定性定量目標的優化比選，得出在嫩江左岸設置胖頭泡蓄滯洪區最優，其優選結果與採用常用經濟評價方法所得結果基本一致，從而第一次用模糊優化理論較全面科學地解決松花江流域防洪工程中確定蓄滯洪區規模這一重大實際問題。Synthetical methods were used to develop an index of comprehensive assessment after flood. firstly, we reviewed the literature extensively and conducted a widely epidemiological investigation on the flood impact on economy, environment, and human health in hunan province, p. r. china after severe flood disaster in 1998. based on the literature review, epidemiologic investigation, and the theory of analytic hierarchy process ( ahp ), the initial evaluation system of flood impact was established, which include six first rank indicators and seventy - four second rank indicators. an expert panel consisted of 30 specialist was convened and delphi process was used to screen and determine all the indicators and their importance ( weight )

摘要針對流域洪水預報和水庫調度中雨量水位站點可能因通信和設備故障引起雨量和水位數據錯誤，而影響洪水預報精度的問題，通過分析水文遙測系統雨水情信息錯誤的原因，研究水文遙測系統雨水情數據的提取、合理性檢驗、錯誤識別方法、雨量插補、數據的智能化糾錯處理等技術。On the basis of the analysis on the yangtze vole ' s disaster history and condition in dongting lake area, the influence of the lake beach ' s environmental evolution on the vole disaster is studicd in this paper. the rise of low - middle - level beach area causes the vole ' s population explosion, the reduction of high - level beach area forces the voles into the farmland during the flood season, and the emergence period ' s continual increase extends the vole ' s habitat areas and forces them to migrate into the farmland. the discarded dike provides a rest place halfway for the voles, which escape the flood, and the natural enemies of the voles, which are a natural barrier against the vole ' s population expansion, decreases. according to this study, the conclusions are put for ward as follows : after three - gorge project ' s construction it will produce great influences on the beach evolution in dongting lake area, leading to the changes of the vole ' s ecological environment situation and resulting in the vole ' s population changes which deserves attention
在分析洞庭湖區東方田鼠暴發成災史及災情的基礎上，研究了洞庭湖區洲灘演變對東方田鼠暴發成災的影響.研究認為，中低位洲灘出露面積不斷增大使東方田鼠種群迅速膨脹，高位洲灘出露面積減小造成汛期東方田鼠大量向垸內農田遷移;湖區洲灘冬春季連續出露天數增加延長了東方田鼠的繁殖期;汛期洪峰水位增高，洲灘大面積淹沒迫使東方田鼠大量遷向垸內;湖內廢棄湖堤為東方田鼠逃避洪水提供了中途休養之地;洲灘地抑制東方田鼠種群膨脹的天敵數量已大大減少.據此，本文指出，三峽工程建成后將對洞庭湖區洲灘演變產生重大影響，因而將改變東方田鼠種群生態環境條件，引起種群動態變化，值得注意These profound experiences are illustrated by no more than a ripple on the surface of ms mcdermott ' s gentle writing, which meanders through the twists and turns of human life like a slow - flowing river
