  1. Abstract : the qiantang estuary with violent hydrodynamic conditions is well known for its tidal bore. the regulation of the estuary in the past, especially the progress since the founding of new china are reviewed. the principles of the regulation and planning of the qiantang estuary formulated in 1960s are expounded, i. e., to narrow the river to reduce the tidal prism, and to increase the ratio of the river flow to tidal discharge. the experience of estuary regulation / reclamation is summarized, especially the engineering measures to protect the groin head and to use polder dykes as sea defense works. finally, the effect is analyzed of the large - scale constraction / reclamation in the estuary on the tides, flooding high water level, estuary bed and the northern deep waterway in the hangzhou bay

    文摘:以涌聞名的錢塘江河口,強勁,破壞極大.回顧錢塘江河口歷代治理情況,重點記述1949年以來治理工作的進展,述60年代提出的錢塘江河口治理規劃的指導思想,即縮窄江道,減少進量,增大山水比值的整治原則.總結整治規劃實施過程中治江圍塗經驗,特別是「以圍代壩」和丁壩壩頭保護等工程措施.分析錢塘江河口大規模治江圍塗后對錢塘江河口、洪水位、河床以及杭州灣北岸深槽的影響
  2. 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 )本項研究首次證了河口三角洲岸線態平衡的概念,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態平衡狀態的重要結; 『 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。
  3. In the tidal estuary, the current is complex, and the flow is oscillatory. some experiential formulation has presented to calculate the vertical turbulent mixing coefficient. on the base of analysis of the hydrodynamic in the estuary, the theoretical equation, which describes the distribution of the space and time of vertical turbulent exchange coefficient, has developed, the equation has applied to the practice

    河口水流呈往復振蕩運,本文在分析河口水特性基礎上,考慮了慣性及重等項的影響,通過理推導得到河口垂向紊交換系數的空間分佈及時間分佈的計算公式,以及垂向平均紊交換系數的時間分佈的計算公式,並將其應用於河口的實際計算中。
  4. The geomechanics based on the change of rotating speed of the earth could answer a large part of the above mentioned questions, but the power which it depends on offered by the expansion or contract of the earth and tides et al is too weak to serve as the energy to change the rotating speed of the earth, so it is also difficult to explain them quantitatively

    基於地球自轉速度變化的地質學理,對之所做的定性解釋頗為合理,但因其只靠地球收縮及等緩變作為引起地球自轉速度變化的來源,量強度太小,不足以引發強大的褶皺造山運,且有被海水運取代的難題。
