摘要
针对龙安河中田、樟溪段河道特征,通过方案比选狭窄河段采用干砌块石+网格草皮堤防,开阔河段直接采用草皮护坡;在缓岸坡非顶河段采用干砌块石+网格草皮护岸,针对冲刷、塌方严重河段采用M7.5浆砌石重力式趾墙+网格草皮护岸;在陡岸坡且冲刷严重河段采用M7.5浆砌块石仰斜式趾墙护岸;平顺段采用草皮护坡。
According to the characteristics of Longan River(Zhongtian,Zhangxi)reach,dry block stone+grid turf dike is adopted in narrow reach and turf slope protection is adopted directly in open reach,while dry block stone+grid turf revetment is adopted in gentle bank non-top reach,and gravity type of M7.5 mortar stone is adopted in serious scour and collapse reach.Toe wall+grid turf revetment;M7.5 masonry stone uphill toe wall revetment in steep bank slope and serious erosion section;and turf revetment in smooth section.
