随着水文工作的加强,巡测方式进一步普及,用巡测车在桥上测流,扩大了资料收集范围。通过桥型选择,桥墩对流速的影响,桥测与其它流量测验方式的对比分析,用具体实验数据和科学计算方法,对桥测流量的精度进行分析研究,寻求桥测与天然流速的关系规律。 With the enhancement of hydrological work, the inspection methods are further popularized, and the rovers are used to measure the flow on the bridge, thus expanding the scope of data collection. Through the bridge type selection, the influence of piers on the flow velocity, the comparison between the bridge measurement and other flow test methods, the experimental data and scientific calculation methods are used to analyze and study the accuracy of the bridge flow measurement and to seek the relationship between the bridge measurement and the natural flow rate .
