1 实施生物护坡的方法1.1 断面设计安阳河市区段河道设计采用复式断面,河底宽58m,一级边坡1:2,平台以上二级边坡1:2.5。考虑到一级边坡以下要满足河道抗冲要求,能通过50年一遇流量设计行洪流速3.1m/s,采用50#预制混凝土六棱板护砌,厚度8cm,边长25cm。一级平台以上至设计堤顶段,因在设计洪水位以上,与主槽相比,淹没机率小,考虑到在满足河道抗冲要求的同时,能起到美化城市环境
1 Implementation of biological slope protection method 1.1 Section Design Anyang River section of the river section design using duplex section, the river bottom width of 58m, a slope of 1: 2, two above the platform slope 1: 2.5. Taking into account the first slope below to meet the river impact requirements, through 50 years of traffic design flood discharge velocity of 3.1m / s, the use of 50 # prefabricated concrete hexagonal board protection, thickness 8cm, side length 25cm. Due to the above design flood level, compared with the main channel, the submergence probability is small, considering that it meets the requirements of the river course impacting and can beautify the urban environment
