ADCP在河道流量测验中的应用及误差分析

摘要

介绍了声学多普勒剖面仪（ADCP）流量测验原理、计算方法。对ADCP与传统测验方法在梧州站的比测试验进行分析，在中、低水流量相关关系较好，中、高水相关性较差，流量越大相对误差越大。探讨了ADCP流量测验中产生误差的原因，并对其误差提出了相应的解决对策。%An introduction was made on the flow measurement principle and calculation method of ADCP. The mea-surement results out of ADCP were compared with that out of traditional measuring method at Wuzhou Hydrological Station. The results out of ADCP have good correlation at middle and low flow while have relatively poor correlation at middle and high flow,i.e. the error increases with rise of flow. The author discussed the causes for the error and put forward corresponding countermeasures.
