摘　　要：为减少和消除高寒条件下振弦式传感器在线测量浸润线的误差,通过理论分析和现场试验,对造成误差的因素及其影响情况进行了深入研究。结果表明,振弦式传感器产生测量误差的主要来源为设备安装深度的测量误差与尾矿水密度及重力加速度的取值误差,并提出了减少或消除误差的方法和工程技术措施,为高寒地区的浸润线在线精确测量提供了重要指导意义。In order to decrease or eliminate the errors in online measuring on saturation line of tailing dam by vibrating-wire sensors under high cold condition, the factors causing error and the effect were studied through theoretical analysis and field test. The results showed that the main source of measurement error comes from the measurement error of equipment mounting depth and the valuing error of railings water density and gravity acceleration, and the methods and engineering technical measurements to decrease or eliminate the errors were put forward. It provides important references for the accurate online measuring on saturation line under high cold condition.
