silting bed 中文意思是什麼
-
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。 -
Based on the topographic features and data of sediment particle size of bed load at the fluctuating backwater reach of liujiaxia reservoir, the streamwise variation and variation process of median diameter of bed load during silting and scouring periods of the fluctuating backwater reach are analyzed, and it can be seen that the turning point for the sediment diameter variation from coarse to fine is located at the outlet of shigou gorge of the fluctuating backwater reach
摘要根據劉家峽水庫變動回水區的河段地形特徵和歷年河床質泥沙粒徑級配資料，分析了變動回水區河段淤積和沖刷時，河床質泥沙中值粒徑的沿程變化和歷年河床質泥沙中值粒徑變化過程，並指出粒徑分佈由粗變細的轉折點在變動回水區寺溝峽峽口處。 -
Because the channel bed was adjusted by scouring and silting in long - term, the required period to reach basically equilibrium was predicted based on the typical and assemble hydrographic data in long series after the building of lijia flume dam
應用李家峽建壩后典型水文年長系列的組合資料，預報了河床經長期沖淤調整后達到基本平衡需要的時間。
