注:快速路、主千路路拱横坡度宜用大值横坡度而组成折线形路拱。纵坡度较缓时路拱横坡度取大值,5.2变方抛物线形路拱根据路拱横坡度i、路面宽度严寒积雪地区路拱横坡度宜用小值。B,采用不同的方次n。n一般为1.25~2.0。本册图集4.1.2非机动车道根据路面类型按表4.1.1-1采用路中n值的选定原则为:拱横坡度。5.2.1为避免拱顶排水不畅,拱顶局部横坡度不小4.2路拱曲线于0.3%,即自拱顶至横距为0.5m处的割线坡度不小于4.2.1路拱曲线形式包括直线形、抛物线形、直线接0.3%;抛物线形、直线接圆曲线形、多折线形。本图集中仅5.2.2为保证行车的舒适和安全,车行道外侧的路列出变方抛物线形路拱、直线接变方抛物线形路拱、拱横坡不宜太大:直线接圆曲线形路拱的计算公式示意图、路拱曲线选取机动车行驶在最外侧车道时的最不利情况进表。由于直线形路拱较为简单,所以未列出路拱曲线行计算,要保证自道路外侧边线至离外侧边线横距为表。因折线形路拱可由以上曲线形路拱取相应的横距、2.5m处的割线坡度在1.5%~2.5%之间变化;选取非机纵距而得,因此,仅列出路拱曲线示意图和计算公式。动车行驶在最外侧车道时的最不利情况进行计算,要4.2.2单向车行道路面宽度B的计算分档间距采用0.5m。保证自道路外侧边线至离外侧边线横距为0.5m处的割4.2.3路拱横坡度i的计算分档取值采用1%、1.2%、线坡度在2.0%~3.0%之间变化;1.5%、2.0%、2.5%。对于变方抛物线形路拱,横坡度小时,适用于5选用条件较宽路面,n取低值;横坡度大时,适用于较窄路面,5.1直线形路拱适用于不同路面类型和路面宽度,对于水泥混凝土路面可根据每块路面板各为不同直线段总说明图集号05WR104理凯表网-乙2c审楼李东校对龙莉药设计袁海幕奶3
