海床沖刷 的英文怎麼說
中文拼音 [hǎichuángchōngshuā]
海床沖刷
英文
seabed scouring-
Vortex - induced vibrations of a submarine pipeline and the concomitant scour around the pipeline with close proximity to an erodible seabed are a complex dynamic interaction between current, pipeline and seabed
摘要海底管道渦激振動和管道周圍海床沖刷是海流管道海床之間復雜的動力耦合問題。With the development of coastal and offshore engineering, the local scour problems are paid more and more attention. however scour in the vicinity of large scale structures founded on seabed have caused destruction to the foundations since the problems have n ' t been studied extensively. based on the principles of local scour around seabed founded large diameter cylinders caused by both waves and currents, the flow and scour processes are investigated in this paper after summarizing and consulting lots of papers and researches existing currently
隨著近海及海岸工程的不斷發展，近海及海岸工程建築物基底附近的局部沖刷問題也逐漸引起關注、重視與研究，但是對波流共同作用下海床上直立大直徑圓柱建築物周圍的局部沖刷研究較少，因而使得坐落在海床上大尺度建築物基底常常受到沖刷而致使基礎受到破壞。During the pleistocene epoch the area that is now tso - chen was repeatedly covered and uncovered by the sea, and the fossilized remains of many organisms were preserved in the sediments that were laid down. today, after each heavy rain the bed of tsailiao creek is left covered with large numbers of fossils
左鎮的菜寮溪流域，由於更新世時為海親海退相互間發生的不安定環境，造成大量死亡的生物形成化石沉積，每逢豪雨沖刷，菜寮溪河床上即散布大量的古生物化石。Primary experimental results indicate that the apparatus is capable of modeling the vortex - induced vibrations of pipeline and the sand scour around the pipeline in typical ocean environments
初步實驗結果表明文中研製的實驗模擬裝置能夠模擬典型海洋環境下海底管道的渦激振動和管道周圍海床沖刷等問題。Based on the data on scour around large diameter cylinders exposed to waves and currents, effects of every kind of sea enviromental parameters on maximum scour depth are analyzed and guided by dimensional analysis and multidimensional linear regression, an equation is given to compute maximum scour depth around large diameter cylinders in combined waves and currents. compared with some other equations, this equation is more accrete, simpler and clearer and the compute d results are in good agreement with experimental ones
本論文主要是在總結國內外研究成果基礎上，從波浪與水流共同作用下海床上直立大直徑圓柱建築物周圍的局部沖刷機理出發，研究和探討了圓柱周圍的沖淤形態；分析各種海洋環境參數對最大沖刷深度的影響，並利用已取得的實驗資料，採用量綱分析原理和多元線性回歸分析方法，建立一個波流共同作用下海床上直立大直徑圓柱建築物周圍的最大沖刷深度計算公式。The reason to creates this kind of destruction to be very many, the main of them is that the apron partially has not been able fully to display it to eliminate energy affect so causes the ditch bed to wash out, forms flushes the pit, leading to the apron, to guard against flushes the trough and both banks slope protection destruction, for a long time, disappear power design of plunge basin and layout have been focused on disappear power. but not to give the enough value on uses the sea to inundate the section to disappear power and adjust speed to reduced downriver washes out
水閘閘下沖刷破壞的部位絕大多數發生在消力池下的海漫和防沖槽處，造成這種破壞的原因很多，其中很大一部分是由於海漫部分未能充分發揮其消能作用而引起渠床沖刷，形成沖坑，導致海漫、防沖槽及兩岸護坡的破壞。一直以來，人們把消能的研究重點放在消力池的消能設計及平面布置上，而對海漫段消能及調整流速功能研究甚少，至於對海漫加糙水流運動建立數學模型，在國內外還很少見相關的論文資料。We have got factor values which influence directly safety and stability, including structure and around wash load structure foundation sink value and liquefaction depth, and we discuss underlying bed response in different marine environment parameters
得到了對構築物安全穩定性有著直接影響的要素值，包括構築物及周邊沖刷量、構築物地基沉降量及液化深度，並且討論了在不同海洋環境參數下的底床響應。分享友人
