摘　　要：通过对实际工程的模型试验,验证了在溢洪道泄槽弯道段上设置导流墙工程措施的合理性,介绍了该工程措施的设计方法: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;导流墙长度可等于或略大于弯道轴线长度,高度可按抬高泄槽底高度Δh的1.0～1.1倍取值;导流墙一般应采用钢筋混凝土结构;导流墙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 rationality of setting of a guide wall on the curved section of the discharge trough was verified by model tests for several practical projects. The method for engineering design is introduced as follows： the guide wall is generally set along the axis of the curved section, starting from the beginning of the curved section; its length can be equal to or a little longer than that of the axis of the curved section, and the height of the wall can be determined as 1.0-1.1 times of the height of the discharge channel bottom to be lifted; with a reinforced concrete structure usually adopted, the rectangular section is suitable for the guide wall, and the top of the wall should be constructed in forms of trapezium or hemieyele so that water can flow over it.
