文摘:以涌潮聞名的錢塘江河口,動力強(qiáng)勁,破壞力極大.回顧錢塘江河口歷代治理情況,重點(diǎn)記述1949年以來治理工作的進(jìn)展,論述60年代提出的錢塘江河口治理規(guī)劃的指導(dǎo)思想,即縮窄江道,減少進(jìn)潮量,增大山潮水比值的整治原則.總結(jié)整治規(guī)劃實(shí)施過程中治江圍涂經(jīng)驗(yàn),特別是“以圍代壩”和丁壩壩頭保護(hù)等工程措施.分析錢塘江河口大規(guī)模治江圍涂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 - The local current disturbance after bridge being built in qiantang estuary leads to correspond changes of riverbed near bridge . but there is not any impact on astronomical tide , runoff large - scaled river shape and riverbed after bridge being built . so it does n ' t change the formation of tidal bore at all after bridge being built , but there is some impact on the shape and intensity of tidal bore because of pier resistance
在錢塘江河口建橋?qū)⒁鹁植克鞯臄_動及近區(qū)河床的相應(yīng)變化,但不會對天文潮、徑流及大范圍河勢、河床產(chǎn)生影響,因而,建橋不會從根本上改變涌潮的產(chǎn)生,但橋墩阻力對涌潮形態(tài)和強(qiáng)度是有影響的。 - Now tidal bore is one of hotspots and difficulty in scientific research . with advanced tide - controlling technology and high accurate equipment , this paper does the research successfully on the formation and changes of tidal bore under natural condition and after the bridge being built . and those processes are observed effectively
涌潮的研究是當(dāng)前的熱點(diǎn)與難點(diǎn)之一,本項(xiàng)研究采用先進(jìn)的潮汐控制技術(shù)與高精度的測試儀器,在比尺模型中成功地模擬出自然和建橋條件下涌潮的形成、變化過程,并有效地加以觀測。 - According to the result of physical modeling , the regression equation about the decrement of tidal bore height , the percentage of water - resisting area and the distance away from the upstream bridge site is constructed in this paper , the regression equation can be applied in the impact which bridge has on the tidal bore height in qiangtang esturary
根據(jù)模型試驗(yàn)結(jié)果,建立了涌潮高度的減小值與中潮位橋墩阻水面積百分比和上游離橋址距離的多元回歸方程,可供錢塘江河口建橋?qū)τ砍备叨鹊挠绊懹?jì)算參考使用。 - It is local impact that bridge being built has on the shape of tidal bore , and this local impact can be recovered in the place which is 300 - 500 long upstream bridge . the impact that bridge being built has on the intensity of tidal bore depends on the water - resisting area of bridge . generally the more water - resisting area is and the nearer the place is away from the bridge site , the more impact is on the intensity of tidal bore
建橋?qū)τ砍毙螒B(tài)的影響是局部的,在橋上游300m 500m的范圍內(nèi)基本可以得到恢復(fù);建橋?qū)τ砍睆?qiáng)度的影響主要取決于橋墩阻水面積,一般來講,阻水面積越大,位置離橋址越近,對涌潮強(qiáng)度的影響亦越大。 - Beginning with the cause of tidal bore , then making use of measure data and combining with scale physical modeling , this paper does the research about the impact that bridge engineering has on the qiantang bore , such as hangzhou bay bridge , guzhu bridge , xiaoshan bridge etc . it provides the scientific evidence for approving those engineering above
