  1. Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status, on special income water and sediment conditions, boundary conditions and oceanic power conditions, this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar, each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate, affect the sediment deposition factors, primary factors are tide prop, the gate widens gradually, estuary gate have branches, brine induced flocculation. this paper study the estuary gate widen, estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data, for the first time, deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception, build the relationship between the estuary income sediment with deposition land area, draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons, the delta coastline may on the dynamic balance status. ( 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,且三角洲與濱區泥沙的沉積比例與來沙密切相關,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,口門西妥理工大工程碩士專業位論文分漢對河淤積的影響進行了定分析: (一扣根據實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; 、 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與造陸面積的相關關系,得出了當河口多年平均來沙維持在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。
  2. The thesis analyzed the present transferring status between pudong airport and shanghai " s incity. through forecasting the long - dated flux of pudong airport and the area near it and combining the planning scheme of shanghai urban rapid mass transit, the thesis learned the helpful experience of the traffic organization in typical airport abroad and used the scientific analyzing model of public traffic flux forecasting to put forward some reasonable suggestion of the bottleneck question between pudong airport and incity : the one is to use the present no. 2 subway as the future airtrain to take on the most part of the flux and meantime present the concept of feeder efficiency to quantitative analyze the choice of feeder station ; the other is to set up cat ( city air terminal ) to convenient the passenger to come airport rapidly and economically in order to lessen the pressure of the traffic and improve the whole service quantity of civil aviation transportation

    本文分析了浦東機場與市內目前的換乘現狀,從預浦東機場及緊鄰空港區域中遠期的客流入手,結合上市政府快速軌交通的規劃方案,並且習境外典型機場交通組織的有益經驗,利用規劃中的公交客流預等科分析模型,對浦東機場與市中心的軌交通銜接提出了合理的建議:一是利用目前的地鐵二號線作為航空軌共享線來承擔大部分進出空港的客流,並且給出了以接運效率最大化為目標函數的接運公交軌站點比選模型;二是在市中心設立城市航站樓以方便旅客快速、經濟地到達機場,從而減少路交通壓力,提高航空運輸的整體服務質
