溢洪道是水库枢纽最重要的组成部分,泄槽设置弯道段是溢洪道工程规划中常见的布置形式。通过对东周水库工程的模型试验.验证了在弯道段上设置导流墙工程措施的合理性.提出了该工程措施设计的方法。导流墙一般布置在弯道轴线上,起始位置与弯道开始位置相同;导流墙的长度可等于或略大于弯道轴线长度;导流墙的高度可取按抬高泄槽底高度△h的1.0-1.1倍;导流墙一般应采用钢筋混凝土结构。断面形式可采用矩形,因导流墙顶部可以过水,顶部宜做成梯形或半圆形。
The spillway is the most important part of the reservoir hub. The curve section of the spillway is a common arrangement in the spillway engineering planning. Through the model tests on the Dongzhou reservoir project, the rationality of the engineering measures of the diversion wall on the curved section was verified, and the method of engineering measures design was put forward. Diversion wall is generally arranged on the curve axis, the starting position is the same as the starting position of the curve; the length of the diversion wall may be equal to or slightly larger than the length of the curve axis; h 1.0-1.1 times; Drainage wall should generally be reinforced concrete structure. Section shape can be rectangular, because the top of the wall can be diverted water, the top should be made trapezoidal or semicircular.
