【摘要】 桥位断面往往与水文断面不在同处 ,通过直观的示意图 ,研究各种流量、水位间的关系。即根据互相制约条件从同一水文断面的不同频率转换 ,到同一规定频率不同断面位置转移的演算过程。提出各种方法 ,进行桥位处设计流量、设计水位的推算更多还原

【Abstract】 This article provides various methods to speculate design of flow and water level in bridge site through studying relations between various flow and water level from the diagram-according to conditions restricted each other from different frequency conversion of the same cross section of hydrology to conversion of different cross section place with the same frequency defined,due to different place between cross section of bridge site and cross section of hydrology.更多还原
