摘要
现行高速公路边坡防护大多采用了衬砌拱进行集中排水的型式,对衬砌拱的流水槽宽度、间距等进行了合理的分析计算,推导了简易的计算公式,特别指出了衬砌拱的流水槽宽度与其间距应具有一定的比例关系,且都与降雨强度、路面宽度以及路面粗度系数等成正比,对衬砌拱的设计应结合高速公路各路段的降雨强度以及路面宽度等实际状况,不应任意设计。给出了部分计算结果表,可供实际工程设计参考。
Arched concrete-bone is used for drainage in most freeways for slope-protection. The width and spacing of drainage ditches of arched concrete-bone are analyzed with a derived formula in this paper. It is pointed out that the width and spacing of the drainage ditches should be in a certain ratio, both of which are directly proportional to rain intensity, pavement width and surface rough-coefficient. In addition, tables are provided as references for design in engineering practice.
