Abstract: Avbstract:Vertical displacement is an important item of safety control for water conservancy project. Existing system can’t execute re-altime monitoring of absolute vertical displacement, the phenmena of entire settlement. This problem can be settled by the absolute vertical displacement monitoring system with the technique of auto-continous monitoring to base point.?

摘要： 垂直位移是水利工程安全监控的重要项目。现有监测系统通常采用双金属标实现实时监测绝对垂直位移即整体沉降现象，本系统采用基点自动连测实现实时监测绝对垂直位移，使用表明，本系统精度高、稳定性好。
