南水北调中线京石段左岸排水工程--石家庄至北拒马河段优化设计

南水北调节器中线京石段渠段总长227.39km,本渠段布置在太行山东麓与华北平原接壤地带,地势西南高、东北低,为此需布置左岸排水建筑物.经过对交叉河流和坡水区的水文分析与计算,结合地形与地质条件综合分析比较,优化了工程布置和建筑物型式,确保了总干渠的防洪安全.

Left bank drainage project on Shijiazhuang-Beijing segment in mid-route of South-North water transfer--Optimal design of Shijiazhuang-Bei Juma river segment

Shijiazhuang-Beijuma River segment in middle route of south-north water transfer project is 227.39km long. It is located in the border of east Taihang Moutain and North-China plain. Since it's higher in southwest and lower in northeast on topography, left bank drainage projects must be laid out. By the hydrology analysis and computation on the cross rivers and catchments areas, compared with the condition of terrain and geology, the layout and structure type of left bank drainage projects were optimized to ensure the safety of the general channel.
