摘　　要：街沟是排除道路路表水的重要设施。街沟设计首先确定计算算法。当雨水口间距为40m时,按照算法1将雨水口处平石边缘标高统一下调m值;当>40m时,推荐了修正的算法1。对街沟挑水点位置与标高,最后进行了综合设计,包括街沟横断面布置,雨水口布设,挑水点确定以及优化设置。It is important of street gutters for the drainage of road surface. The computational algorithm of street gutters is determined firstly. When the spacing of gullys is 40 m, variable m will be reduced about the plane curb elevation of gutters according to algorithm 1. When the spacing is larger than 40 m, the correctional algorithm 1 will be recommended. There is an integrated design of the raised curb location and elevation of street gutters, including its cross section layout, gullys set up, determination and optimization setting of the raised curb.
