摘要
以西南水运出海北线通道航道建设工程为依托,综合分析多个已建库区多年实测水位资料,得知枢纽成库后综合糙率将有所减小,在接近设计流量时成库后综合糙率与成库前糙率比值为0.862。将上述成果运用于洋溪、梅林等规划枢纽库区沿程设计最低通航水位计算中,与实际较为符合。
Based on the channel construction project of the north channel for the southwest water transport, we analyze measured data of many years on the water level of multiple existing reservoirs, and get to know that the comprehensive roughness will be reduced after completion of the water conservancy, and the ratio of the channel's comprehensive roughness after completion of the water conservancy to the natural river is 0. 862. Using the results to calculate the designed minimum navigable stage of Yangxi and Meilin reservoir, it shows that the calculation result accords well with the natural conditions.
