桥上测流实例经验分析

水文站网中,部分测站受条件限制,汛期无法利用测船和缆道以流速仪法进行流量测验,因此,在汛期高洪测流时部分测站选用邻近测验断面的公路桥进行流量施测。文章就桥上测流的优越性和实际工作体会进行了分析论述,对实例测站桥测实践经验进行了总结,为今后进一步推广使用洪水期桥测经验提供了参考。

In the hydrologic station network,some stations are restricted by the conditions,so it is impossible to use the method of velocity meter to measure the flow of the ship and the cable in flood season.Therefore,some stations choose the highway bridge adjacent to the test section to carry out the flow survey during the flood season.In this paper,the superiority and practical working experience of bridge flow measurement are analyzed and discussed,and the practical experience of bridge survey at practical station is summarized,which provides a reference for the further popularization of bridge survey experience in flood period
