摘　　要：为研究探讨平纵曲线处高速公路中央分隔带防眩设施的设置,充分结合平面直线路段防眩设计和防眩角公式,根据平面几何原理及三角函数相关定理,推导论证得出求解平面圆曲线遮光角和防眩设施间距以及竖曲线防眩设施设置高度的理论公式,便于高速公路中央分隔带防眩设施的设计成果复核验算和运营养护实际应用,有利于消除夜间由眩光引发的交通事故隐患,保证车辆行驶运营安全。In order to study and explore the layout of anti-glare facilities in the central divider of the expressway on the horizontal and vertical curves,combining the tangent section anti-glare design and antiglare angle equations,the theoretical formulas for solving the anti-glare angle and spacing of anti-glare facilities on the plane circular curve and the installation height of anti-glare facilities on the vertical curve are deduced and demonstrated according to the plane geometry principle and the related theorem of trigonometric function,which is convenient for the design results of the anti-glare facilities of the central division of the expressway to be checked and the practical application of operation and maintenance,and is conducive to eliminating the hidden dangers of traffic accidents caused by glare at night and ensuring the safety of vehicle operation.
