rigid bed model 中文意思是什麼
rigid bed model
解釋
定床模型-
Because it is relatively reliable in both theoretical and practical research, the rigid bed model, which is without deformation under the action of river flows, is widely used in the river hydraulic simulations. the advantages of visibility and high accuracy of the rigid bed models are evident for the complicated boundary conditions of rivers
在河道水力模型中，尤以河床在水流作用下不發生變形的定床模型應用最為廣泛，在理論上和實踐上都已比較成熟，當河段的邊界過于復雜時，其直觀、準確的優越性更為明顯。 -
The resistance coefficient of the river, the scale affect of the rigid bed model, and the rule of channel dredging are also discussed in order to obtain the reliable conclusion
對河床的阻力系數、定床模型試驗的比尺效應以及電廠下。游清挖原則進一步研究，以期給出較明確的結論。 -
When elastic pile model is employed, the depth of the piles embedded in the slide bed is relatively large, whereas the dimensions of the pile body are relatively small. nevertheless, if rigid pile model is employed, the situation is reverse
採用彈性樁方案時樁的埋深較大，但樁身截面可適當減小；而採用剛性樁方案，樁的埋深淺，但樁身截面大。 -
However, the rigid bed models are also limited by several shortcomings, such as the large quantity, the long period, and the high costs. moreover, the resistance similarity, the distorted ratio, and the model scale are also with problems
但定床模型試驗除有工程量大、周期長、費用高等局限外，還存在阻力相似、變態率和模型比尺的限制等問題，因此有必要進行深入細致的研究。 -
Owing to the reasons mentioned previously, the investigation in this paper is focused on the several aspects as follows : 1 the limitation of the design method, distorted ratio, and model scale of the rigid bed model are described
鑒于上述原因，本文所進行的工作主要集中在下面幾個方面： 1闡述定床模型試驗的設計方法、變態率和模型比尺的界限，並結合太平灣電廠的具體情況，說明其定床模型設計的考慮方法，給出了試驗結果。
