导流墙对弯道横断面水面差影响实验
Experimental analysis on the influence of diversion wall on the surface difference of cross section of bend
摘要
Abstract
In order to study the effect of improving water flow in bend of spilling chute using diversion wall ,hydraulic model ex‐periments with diversion wall were carried out under different hydraulic conditions in this paper .The results showed that :After setting diversion wall ,the surface difference of cross section in concave and convex banks was significantly lower than that in the absence of diversion wall ,but the surface difference still existed ;Variation of the surface difference was the same as that without diversion ,the surface difference increased with the increase of flow rate and bottom slopes ,and decreased with the in‐crease of the radius of bend ;After setting diversion wall in the bend of spillway chute ,the position of the maximum surface difference changed .The maximum surface difference was seen in the vertically adjacent section of middle bend in the presence of diversion wall ,whereas in the upstream section before middle bend in the absence of bend .关键词
