摘要
利用水力学原理及经验公式对不同形式的边沟以及不同形式的排水口进行了深入分析.对于边沟主要确定了具有单一横坡和复合横坡断面的水流量计算公式;对排水口,综合考虑了边沟内水流量、铺面横坡、纵坡、边沟内设置低洼区等因素对其排水能力的影响.确定了排水口在连续坡段上不同形式的排水口在不同条件下的截流率,从而得出了设计表面排水系统时连续坡段上宜采用的边沟和排水口形式.
Using hydraulics principle and experiential equation, different gutters and inlets are alalysed deeply. To gutter, the equation of single section and composite section to compute water flux is confirmed ; To inlet, interception capacity affected by water flux in gutter, cross slope, longitudinal slope and depressed gutter is considered. Based on the result, the interception capacities on grades of different inlets in different conditions are confirmed, and at last, the right type of gutter and inlet in pavement surface drainage design is commended.
