rigid bed
解釋
固定河床-
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。 -
At present, limit equilibrium method is one of the conventional slope stability analysis methods. it ca n ' t consider nonuniformity of mechanical characteristic of landslide body and its rock bed and the effect of stress distribution on the gilding surfaces, since the rigid body assumption is adopted in this method. furthermore, this method ca n ' t accurately consider inactive forces between slices
目前常用的邊坡穩定分析方法中的極限平衡法由於採用了剛體假定，無法考慮塌滑體及其基巖力學特性的不均勻性和滑動面上應力分佈的影響，此外還不能準確考慮條塊間的作用力，而另一種常用的邊坡穩定分析方法? ?常規有限元分析方法，當滑動面全部處于屈服狀態或邊坡的實際抗滑穩定安全系數小於1時無法求解。 -
The complex foundation of the rigid pile coexisted with the flexible pile is a new technical way of the foundation bed treatment and it is a studying hot point for the academic and engineer circles about this aspect
摘要剛性樁與柔性樁共同作用的復合地基是一項新的地基處理技術，是現在學術界和工程界研究的熱點。 -
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。
