摘要
该文结合实际工作经验,把公路桥涵水文计算方法作为研究对象,分析了桥涵水文计算的内容、基本要求和计算、分析的基本途径。只要是从事桥涵水文有关工作的人员,就应该明白:桥涵水文调查作为公路工程外业调查的基础工作是确定合理的桥涵孔径和控制工程规模的主要依据。并且应从设计流量、桥梁形态断面及洪水位、大中桥孔径和河床冲刷深度四个方面,来讨论水文计算方法的具体应用。
According to the practical experience, the article analyzes the contents, basic requirement and calculation and basic analysis way of hydrological calculation of bridge culvert. It should be understand that the hydrological survey of bridge culvert as the basic work of highway engineering field survey is the main basis to determine the reasonable bridge culvert aperture and to control the engineering scale. The article discusses the detail application of hydrological calculation method from five aspects of design flow, bridge configuration section, flood level, middle-large bridge spans and riverbed scour depth.
