摘　　要：为使混凝土护栏能够更好地与周边环境相协调,达到安全与美观的双重效果,开展混凝土护栏景观提升设计研究。提出墙体涂装型、墙体刻槽型、墙体开孔型混凝土护栏3种景观提升方法,利用仿真计算分析方法或实车足尺碰撞试验方法对景观提升后的护栏安全性能进行了验证,结果表明:对于墙体涂装型混凝土护栏,墙体有、无涂装对其安全性能未产生实质影响;对于墙体刻槽型混凝土护栏,凹槽的边缘坡度、深度及楞间距对护栏的安全性能具有一定影响,在楞间距相同的条件下,凹槽的边缘坡度越大,可容许的深度越大,但不得超过深度规定限值;对于墙体开孔型护栏,在开孔中心间距相同的条件下,孔下沿距路面高度越高,可容许的开孔高度越高,但不得超过孔高规定限值,在护栏开孔下沿距路面高度相同的条件下,孔中心间距越大,可容许的开孔高度越高,但不得超过孔高规定限值。In order to make the concrete barrier better coordinate with the surrounding environment and achieve the double effect of safety and beauty,the research on the landscape enhancement design of concrete barrier is carried out.From the perspective of highway design aesthetics,in the paper,the design principles and design ideas of concrete barrier landscape enhancement are summarized.On this basis,three landscape enhancement methods of wall painting type,wall carving type and wall opening type concrete barrier is proposed,and the safety performance of the barrier after landscape enhancement is verified by using simulation calculation and analysis method or full-scale impact test with real vehicle.The results show that:for wall painted concrete barrier,wall with or without painting has no substantial impact on its safety performance.For wall grooved concrete barrier,the edge slope,depth and spacing of the groove have a certain impact on the safety performance of the barrier.Under the condition of the same spacing of the groove,the greater the edge slope of the groove,the greater the allowable depth,but the depth should not exceed the specified limit.For the wall open-hole barrier,under the condition that the opening center spacing is the same,the higher the lower edge of the hole from the road,the higher the allowable opening height,but shall not exceed the specified hole height limit;under the condition that the lower edge of the fence is the same height from the road,the greater the hole center spacing,the higher the allowable opening height,but shall not exceed the specified hole height limit.These three landscape lifting methods provide reference for the landscape design of highway concrete barrier.
