张家界观光电梯监测系统的设计与运行效果

The Designing and Operation of the Monitoring System for the Tourist Lift in Zhangjiajie

张家界观光电梯为目前世界上最高的户外观光电梯 ,在设计、施工和监测等方面尚没有规范和技术资料可循 ,要求电梯及其所依附的山体的容许变形值极小 ,变形的观测精度不大于 1.5mm .以常规的监测方法难以满足精度要求 .为此运用了多点位移计、钢筋应力计等先进技术 ,建立了SMDAMS亚毫米级高精度空间自动监测系统 .介绍了该监测系统的设计、实施及运行情况 。

The tourist lift in Zhangjiajie is the highest among its kind in the world of today,and so no technical standard or example can be followed in designing,constrution and monitoring.The tolerant deformation values of the lift and the mountain body it relies on are very limited,and the accuracy of observation is required to be below 1.5 mm.As the conventional monitoring method cannot meet the required accuracy,much advanced means like the multipoint displacement sensor and steel stressometer,etc.,are used,and a submillimeter-accuracied automatic spatial monitoring system has been established.An account of this system is given here about its designing and operation,which can serve as a reference for the like facilities.
