摘　　要：结合额木尔河大桥工程实例,对额木尔河大桥水文计算进行简单分析。本次水文计算采用频率分析法和形态断面法两种方法确定设计流量,并根据设计流量推算设计水位、设计流速和最小桥长,计算壅水、浪高,确定桥面最低高程。This paper analyzes hydrologic computation of Emuer river bridge combined with engineering practice.It uses frequency analysis and shape section method to determine design discharge,the design level,flow rate and minimize length was computed according to design discharge.The damming and wave high was computed and bridge lowest elevation was determined.

关 键 词：水文计算 设计流量 设计流速 设计水位
