走航式ADCP在外业测量中的应用

声学多普勒流速剖面仪（简称ADCP）是当今最为先进的在线流量测验仪器之一,由于其测验精度高、数据信息详细、完整,而且在外业测量中方便、快捷等特点,在水利工程测量及水文测验中得到广泛使用,测验技术也日趋成熟。但ADCP在实际使用中受到一些客观条件的限制,特别是断面形态及水流情势的限制,影响了使用效果,本文就ADCP在水利工程测量中遇到的一些技术问题及处理方法提出来与业内人士进行探讨。

The application of ADCP in outdoor measurement

Acoustic Doppler Current Profiler(ADCP) is one of advanced current measurement instrument today,due to it is a sonar that attempts to produce a record of water current velocities for a range of depths,and has high measurement accuracy,and detailed data,integrity,which is convenient applied in outdoor measurement,fast and so on,widely used in hydraulic engineering surveying and hydrological test;the test technology is becoming mature with time;but ADCP application has be limited in actual by a number of objective constraints,especially the cross-section shape and flow restrictions of the situation,which influence the effect of the use of ADCP.This paper discussed the some technical problems encountered in measurements of hydraulic projects and put forward the treatments for internal reference.
