冲刷

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。

The result shows that the erosion presents as incision when the riverbed is relative narrow and deep; To the low-water branching reach with strong boundary conditions where the riverbed is wide and shallow, the scour and deposit variation characteristics mainly presents as erosion and deposition adjustment of river island, height deviation of thalweg in the inlets and the adjustment of split ratio after impoundment To the low-water branching reach where the riverbed is wide and shallow and the lateral boundary conditions are weak, the scour and deposit variation characteristics is not restricted to the adjustment of split ratio, and the pattern of the braided reach may even be changed.

结果表明：当河段相对窄深时，河段冲刷主要为下切；当河段为相对宽浅的低水分汊河段且河岸约束较强时，蓄水以后的冲淤变化主要体现为江心洲滩的冲淤调整、汊道深泓高程差的冲淤调整，并引起主支汊分流比的调整；当河段为较为宽浅的低水分汊河段且河岸约束相对较弱时，则冲刷调整不仅限于分流比的调整，甚至会导致大的分汊格局的调整。

The different points of views, transverse section, plane and volume changes are considered. The results show that the evolution of the Xinqiao Channel has experienced three stages: in 1861~1926 ,the Xinqiao Channel area had been eroded at first and then silted; the Xinqiao Channel is formed during 1926~1958 with the channel experiencing persistence erosion; from 1958 to 2002, the total volume of the Xinqiao Channel keeps stable with the volume of 5.02×108m^3. The pattern of 10m contour has shaped to a certainty in 1926 and 5m contour of the upper and lower parts of Biandansha has been joined. The change of sections of the Xinqiao Channel reflects its thalweg movement to the North Bank 1.1~2.8 km, its shape changes from "U" shape to "V" shape and its depth has been deepened.

计算结果显示在所研究的区域内自1861年以来新桥水道冲淤过程明显被分为三个阶段：1861~1926年的66a间新桥水道区域经过一段时间的冲刷后又重新产生淤积，总容积变化不大；1926~1958年的33a间新桥水道在不断的冲刷中总容积由2.603亿立方公尺增长到5.076亿立方公尺；1958年至今的45a时间里水道容积基本保持在平均5.02亿立方公尺。1926年新桥水道10m等深线已经形成一定的格局，1947年5m等深线向上延伸，扁担沙已经不再与崇明岛相连；1958年上下扁担沙的5m等深线基本连成一体，可以认为此时新桥水道已经形成。
