摘　　要：本文对急流弯道上的斜槛设计进行了研究。首先阐述了弯道上斜槛控制超高的原理,并根据此原理给出了斜槛的设计公式,提出斜槛的的设计方法。工程实例表明,本文给出的方法是合理的。同时对斜槛的高度、长度、形状、斜槛的间距、斜槛与水流方向的夹角等影响设计因素进行了探讨,这有利于斜槛在实际工程中的运用。This paper deals with the sills in curved channel. The theory of sills against flow freeboard in curved channel is expounded. Based on this theory and the momentum equation, the design formula for calculating the length of sills is derived, and the design method is presented. The reasonability of the method is verified by field tests. Furthermore, on basis of the formula, the correlation factors of sill such as its height, length, shape, spacing and the included angle between sills and flow directions are discussed. It is useful for engineering design.
