( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method
研究認為： （ 1 ）黃河河口口門逕流潮汐區域並非持續保持淤積狀態，在特定的來水來沙、邊界條件和海洋動力條件下，該區域可以處于沖刷狀態； （ 2 ）從河口泥沙沉積分配的過程來看：三角洲與濱海區泥沙的沉積變化趨勢是基本一致的，各部位的泥沙沉積比例變化基本呈波動狀態，且三角洲與濱海區泥沙的沉積比例與來沙量密切相關，基本成正比關系； （ 3 ）在口門處，影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等，本報告主要對口門加寬，口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: （一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式，據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 ）本項研究首次論證了河口三角洲岸線動態平衡的概念，並建立了黃河河口來沙量與造陸面積的相關關系，得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 ）本項研究首次提出了河口泥沙優化調控的概念，並對其宏觀優化調控模式進行了初步探討。Regarding natural sand of the spot as model sand, using series model, and under the interaction of irregular wave and tidal current, a systematic test on scouring around pile of land - island approach bridge of jiangsu lng receiving station is carried out
摘要以現場天然沙為試驗床質，利用系列模型，採用不規則波與潮流相結合的方式，對江蘇lng接卸站陸連島橋樁基周圍的沖刷情況，進行了系統試驗。All negative landforms, which are shaped by flood - dominated current, such as souring hole, scouring channel and flood channel, are belong to the study area of flood channels
通過以上的研究認為河口漲潮槽的概念應該有更為廣泛的含義，包括河口一切由漲潮流作用為主形成的負地形，如漲潮沖刷坑，漲潮沖刷槽和漲潮水道等，漲潮槽的特徵應該保持多年。This paper presents a method of probability analysis in order to develop the general design and analysis methods for problems of the embankment stability under random storm wave actions as well as with random properties of the embankment medium. the major purpose of this study is carry out modellings of ( 1 ) probability analysis for the problem of seepage stability of levee projects ; ( 2 ) probability analysis for the problem of erosion due to washout sediments from the embankment ; ( 3 ) numerical analysis for coastal evolution due to beach erosion under energy actions of storm wave
