无浮托引张线在葛洲坝大坝变形监测中的应用

Application of the Non-floating Tension Wire Alignment Method in Deformation Monitoring of Gezhouba Dam

基于无浮托引张线的工作原理,分析葛洲坝无浮托引张线自动化监测系统运行监测资料,并与传统人工观测数据以及步进电机式、电容式引张线系统进行对比分析表明,无浮托引张线自动化监测系统自动化程度高、系统运行可靠性高、测值精度高,能更真实反映大坝变形。

The application of the non-floating tension wire alignment method in deformation monitoring of Gezhouba Dam is introduced.After an introduction of the working principles of the non-floating tension wire alignment method,the performance of the automatic deformation monitoring system with the non-floating tension wires in Gezhouba Dam is analyzed and compared with the traditional manual observation method,and the stepping motor type and capacitor type tension wire systems.The results show that the automatic deformation monitoring system with non-floating tension wires is of advantages such as high degree of automation,high operation reliability and high accuracy of measurement,which can reflect the deformation of the dam exactly.
