河道中心线和纵坡设计是河道整治规划设计的关键。结合岚漪河河道的工程地质和地形条件,确定河道中心线河道纵坡,选取了5个计算断面确定洪峰流量,并利用明渠槽恒定均匀流公式计算河道水深和河道宽度,为岚漪河河道整治顺利实施提供依据。
River centerline and longitudinal slope design is the key to river regulation planning and design. Combined with the engineering geology and topography conditions of Lanyi river, the longitudinal slope of the river center is determined. Five calculated sections are used to determine the peak flow and the channel depth and channel width are calculated by the constant flow equation of open channel. Rehabilitation provided the basis for the smooth implementation.
