基于适用性试验的ADCP应用价值与制约因素分析

ADCP Application Value and Restraining Factor Analysis Based on Employment and Suitability Test

选择具有高含沙、水草、漂浮物、浅水高(低)流速等复杂测流环境的典型水文站点,对引进走航式、固定式及便携式声学多普勒流速仪(ADCP)进行适用性试验。结果表明:ADCP在一定水流条件下测验精度和测验效率更高,应急监测和机动能力更强,但受到使用成本、可靠性、技术培训、运行维护、比测率定以及与《水文资料整编规范》协调等问题的困扰,仍然没有在国内得到大规模推广应用。消化吸收其先进技术,研究开发国内同类产品,制定相应的技术指标体系,是从整体上提高我国测流技术水平的根本途径。

The typical hydrological sites with the complex flow gauging environment of high sandiness, aquatic plant, floatage, shallow water high( low) flow rate are selected, for the employment and suitability test of the importing vessel- mounted type, stationary type and portabletype of the Acoustic Doppler Current Profiler( ADCP). The results show that the higher the test precision and test efficiency in some flow conditions, the stronger the emergency monitoring and mobile abilities will be. However, influenced by the usage cost,reliability, technical training, operating maintenance, compare measurement and calibration, and the issues related to the coordination of the Hydrological Data Compilation Specification, it has still not been greatly popularized and applied in domestic market. To improve our country's flow gaging technology level on the whole, we shall take the basic solutions including digesting and absorbing its advanced technology, researching and developing domestic similar product and formulating the corresponding technical indexes system.
