摘要
H-ADCP作为多普勒测量仪器,在仪器应用过程中必须要解决一些特定的技术问题,才能提高水文测验精度。针对平原河网地区特点,以太浦闸水文站H-ADCP的应用为例,对H-ADCP安装断面、型号、换能器位置的选择、水位数据的引用等主要技术问题进行探讨,通过比测、参数率定和误差的分析,说明H-ADCP对于解决太湖流域因潮汐影响导致河水流向往复不定、水利工程建设速度较快导致水流受调度影响大等难题具有较好的效果,应当在平原河网地区的水文测验工作中推广应用。
As a Doppler measuring instrument, H-ADCP must solve some specific technical problems to improve the hydrological precision in the course of application. Aiming at the characteristic of plain river network area and taking H-ADCP application in Too pu gate hydrological station for example, the article discusses on the choice of installation section, model, transducer＇ s position and the quote of water level data. By comparing, rating parameters and analyzing error, it explains that H-ADCP can well solve the problem of river direction reciprocating uncertainty and flow influenced by scheduling. H-ADCP should be widespread used in the hydrological work of plain river-net area.
