摘要
ADCP等测量新技术用于金沙江河道,取到了宝贵的成果,但GPS在山区使用受到限制,ADCP和测深仪会受含沙量影响不能满足测量需要,以及电波流速仪因电磁辐射干扰阻碍使用等。为此,通过分析仪器原理和环境条件,提出了一些有效的处理办法,并在实践中得到成功运用。
New technologies such as ADCP can be applied to the riverway of Jinsha river and we have achieved valuable results. But GPS may be restricted in the mountainous area., ADCP and depth measurement meter not be able to meet the need due to sand. Use of Electric Wave Flow Meter is also obstructed because of electro-magnetic radiation. Through analyzing instrument principles and environmental conditions, we have proposed some efficient methods and have successfully applied them in practice
