摘要
阐述了一种以光纤Bragg光栅(FBG)传感器为基础,且适用于挡土墙侧向变形监测的KLA—1型变形监测计,并详述了该监测计的基本结构、监测原理及相关计算公式。以某厂区挡土墙的变形监测为例,给出了此种变形监测计的监测效果,并对挡土墙的整体稳定性进行了总体评价。
A new type of deformation monitoring gauge for retaining wall monitoring based on fiber Bragg grating sensor is introduced. The basic structure, the monitoring principle and the related formula about this gauge is described. The application of the gauge in a retaining wall is given, the related monitoring curve is presented, and the overall stability of the retaining wall is evaluated according to the monitoring curve.
