摘 要: | 大坝安全监测所用的振弦式测力监测仪器一般采用四芯屏蔽电缆实现信号输入和输出。”一带二”技术是在实际工作中根据施工现场的需要总结出来的一种应急补救措施。当振弦式仪器的信号电缆在埋设施工后,发生电缆故障时可以采取该技术措施来进行补救处理。试验结果表明监测信号完整且相互之间无干扰。

Abstract: | The four-core shielded cable is generally used for the vibrating force monitoring instrument to implement signals input and output in a dam safety monitoring. The technology of one cable connecting two vibrating wire force sensors is a kind of emergency remedial measures obtained from the practice to meet the need of jobsite. The remedy can be adopted to deal with the cable faults occurred after the signal cables of vibrating wire instrument are pre-buried. The testing results show that the signals measured are intact with no interference one another. |
