混凝土支墩平板坝变形监测系统改造

Reconstruct of Dam Deformation Monitoring System of Concrete Pillar Faceplate Dam

古田溪三级大坝变形监测系统改造是在混凝土支墩平板坝且运行近40年的老坝上进行的．正倒垂、引张线、静力水准、裂缝等自动监测仪器均为国产的步进马达光电跟踪式遥测仪，系统改造后．每天监测一次．系统运行至今，能达到自动化监测的目的。同时为国内同类型坝的自动化监测系统改造提供经验借鉴。

The dam deformation monitoring system was reconstructed on the faceplate dam with concrete support piers, which was put into operation as long as 40 years. The new system have the instruments of inverted plumb line, flatting wire, static water level, cranny meter and so on, which could be auto monitored by a stepping motor made in China. After reconstruction, dam deformation status was monitored automatically once a day since the system completed. The experience may provide some reference for similar auto- monitoring system.
