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:以涌潮聞名的錢塘江河口,動力強勁,破壞力極大.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,論述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,減少進潮量,增大山潮水比值的整治原則.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潮汐、洪水位、河床以及杭州灣北岸深槽的影響Through checking computations, it was shown that the analogue accuracy of the model was quite high, which can provide important basis for scientific decision - making on engineering measures. through analogue calculation and analysis of many regulation schemes, it was shown that combining the diversion weir works with the bed fixing works at the south branch is reasonable and feasible in the implementation of loushuikouzi river regulation works. in addition, it is suggested that the bed fixing works at the south branch should adopt the improved compound section scheme
經對多個整治方案的模擬計算與分析,表明漏水口子河道整治採用分流魚嘴工程和南汊固床工程相結合的整治工程措施是合理可行的,通過模型計算研究還提出了南汊固床工程採用復式斷面形式的改進方案建議,該方案保證了南汊枯期通航和不斷流,而且對南汊及撫遠鎮的保護具有正面作用。Based on the riverbed evolution analyses of the downstream reach of oujiang estuary and physical model test of eight types of regulation projects, an estimation method for nondeposit velocity satisfying channel depth is presented under fixed bed model test condition
摘要通過對甌江口外段河床演變分析,以及8種航道治理工程的物理模型試驗,提出了在定床試驗條件下滿足航道水深所需的不淤流速的估算方法。This was a particularly severe problem in the lower shing mun river in sha tin, but dredging and a bio - remediation project undertaken in 1997 made a huge difference to the smell of the river
沙田城門河下游以往曾有河水發出惡臭的問題。政府於1997年治理河道,在河床口進行挖掘污染沉積物工程及利用生化處理方法改善沉積物質素,難聞氣味已較以前大幅度減少。In the past decade, we built a total of some 31 kilometres of concrete channel bed in 16 major river training and flood prevention projects ( see annex 1 for details )
在過去十年,我們在16項主要河道治理及防洪工程中建造共約31公里混凝土河床,詳見于附表一。In order to explore harness scheme, layout, measurements and parameters concerned of the project, which are appropriate for the characteristic and the evolvement law of the watercourse of ningxia section of the yellow river, the study on the experiment of the scoured pit of the dam buttress and runoff of the root rock of ningxia section of the yellow river is of important theoretical meaning and practicable value
河道床質也不相同,仁存渡以上河段為沙卵石,以下河段為沙質。為了探索適宜黃河寧夏段河道特性和演變規律的整治方案、工程布局、工程措施及有關參數,開展黃河寧夏段河道壩垛沖刷坑和根石走失試驗研究,具有十分重要的理論意義和實用價值。Abstract : for high arch dams in valleys with the characteristics of high water head, large discharge and large power, the problems of energy dissipation and scour prevention are serious. based on scientific studies, new comprehensive measures are proposed, including dispersion of discharge to waken wallop of the current, and reinforcement of riverbed to enhance the erosion - resistance. the measures can be used to solve the problem of energy dissipation properly. a typical layout scheme has been proposed in which slotted bucket with diversion teeth, double deck with pores, and cushion pool are considered practice has proved that the scheme is reliable and the effect of energy dissipation is obvious
文摘:高拱壩泄洪消能的特點是壩高落差大,流量大,功率大,位於河谷狹窄地區,泄洪消能與防沖問題突出.經科學研究,採用「分散泄洪,削弱水流沖擊力,加固河床,增強河道抗沖能力」的綜合治理措施,較好地解決泄洪消能布置問題.提出了表孔大差動坎加分流齒、雙層多孔、水流撞擊、下設水墊塘聯合消能的典型布置方案,經實踐證明,方案可靠,消能效果好Especially for resent years, because the conditions of coming discharge and sediment have occurred un - corresponding variation, shrink ' s velocity increases serious rapidly, shrink ' s characters tend to be serious, the river bed have been heightening continuously, from these, they have lead to various disaster effects obviously and brought heavy pressure for flood control and river harnessing
黃河下遊河道為嚴重的萎縮性河道。尤其是近年來,由於來水來沙條件發生非協調性變異,萎縮速率明顯加快,萎縮性更趨嚴重,河床持續抬高,由此引起的各種災害效應愈加明顯,對防洪及河道治理產生巨大壓力。Test results show that spur dikes aligned along a single bank in the deep water zone have more effects on the adjustment of the bed topography of the wide - shallow river than in the shallow water zone ; alignment of spur dikes along both banks can effectively adjust the planimetric position of deep - water zone ; and a reasonable widening rate of the regulation line in the estuary can readjust the variation of the average water depth along the river
試驗結果表明,在深水區的單側丁壩群對寬淺河床地形的調整作用大於淺水區;雙側丁壩群的聯合作用能調整深水區的平面位置;合理地選擇治導線的放寬率,能有效地調整深槽平均水深的沿程變化。By use of the morphological coefficients of estuarine riverbed and the relevant data of the north channel of the yangtze river estuary, the widening rate of the regulation line of the north deep - water channel of the yangtze river estuary is calculated, and the calculation result is in agreement with that of the fixed bed model test
