查询词典 scour

For the experimental results under the steady flow conditions, the scour hole and local scourdepth are comparatively small for both a eccentric and concentric non-uniform piers.Since the scouring retardation by the top of foundation and the distance between thetop of foundation and the initial bed level, the downflow intensity is reduced for theun-exposed bridge foundation (Y=+10mm).

研究结果显示於定流量作用下，不论是非同心圆或同心圆不均匀桥墩，当桥墩基础未裸露(Y=+10mm)时，由於覆土高与不均匀面之影响，而减缓向下射流之强度，因此所产生之冲刷坑大小及冲刷深度较小。

This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

本文介绍了平面二维水流二维模型研究进展，对河道历史演变概述，通过最新原型观测资料对河道近期主泓线、断面、洲滩、河床冲淤、码头附近冲刷坑等进行详细分析，总结近期河道演变规律，并参考有关文献，对三峡建成后河道演变趋势进行预测；建立了平面二维水流模型，并根据最新资料对模型进行率定和验证，采用模型对几种工况组合进行壅水和流速计算；采用国际上广泛应用的Geo-Slope滑坡稳定分析程序对几种工况条件下工程断典型断面岸坡进行稳定性计算；最后总结工程建设对洪水位、流速、河势、堤防及防洪抢险等方面进行综合评价，得出码头建设对行洪影响较小的结论。
