河槽沖刷 的英文怎麼說
中文拼音 [hécáochōngshuā]
河槽沖刷
英文
channel erosion-
Then river width increased and the intensity of deep point lowing and bed material coarsening decreased and water level lowed continuously. so the bed form changed toward to u type. the bed regulation is realized through sediment silting in different parts in cross section during silting period and the deformation of bed form changed from broad u type channel to narrow and deep v type channel
研究表明，河道在持續沖刷前期深泓點及水位下降與河床粗化同步發展，河床向v型發展；沖刷後期深泓點下降、河床粗化減弱，河道展寬增大，水位繼續下降，河床向u型發展；在以淤積為主時期的調整，是通過斷面不同部位的淤積來實現的，但都是由u型較大河槽向v型窄深小槽發展。The characteristic of bed regulating is that the width and area of main channel and medium flowing channel increased greatly during the sustained silting period and decreased during scouring period
河道調整特點為持續沖刷時期主槽、中水河槽的河寬、面積都明顯增大，持續淤積時期則減小。5. based on the physical model, summarized the general mode of river development in excavated segment with its up and lower influence reach after dredging, it means that gradually deposit in dredging segment while wash out in up reach, and the change intensities are weakening as the time goes on
概括總結出了河段疏浚挖槽后，疏浚挖槽河段及其上下影響河段的河床演變及水面線變化的模式，即挖槽段逐漸回淤，挖槽上游段逐漸沖刷，並且其回淤及沖刷的強度隨時間的推移由大變小。All negative landforms, which are shaped by flood - dominated current, such as souring hole, scouring channel and flood channel, are belong to the study area of flood channels
通過以上的研究認為河口漲潮槽的概念應該有更為廣泛的含義，包括河口一切由漲潮流作用為主形成的負地形，如漲潮沖刷坑，漲潮沖刷槽和漲潮水道等，漲潮槽的特徵應該保持多年。Through the experiment, four engineering questions are answered : 1. whether the notching construction can be done on the wet beach of the downstream of the yellow river with the blasting method ; 2. whether the ditches can be created by the blasting and how long can be maintained ; 3. whether the ditches can be used to divert water and form a new river channel by water flushing ; 4. the impacts on the safety of the existing projects therein from the blasting concerned
通過試驗，回答了在黃河下游濕灘上能否進行爆破開槽施工；爆破能否形成溝槽，形成的溝槽可以保持多長時間；能否作為引槽引水，通過沖刷形成新河槽；爆破開槽對已有工程的安全影響等四方面的問題。分享友人
