摘要

山区公路运营过程中

须掌握重力墙位移的变化

保障公路的安全。通过对重力墙作有限元分析

确定监测区域

并在墙监测区域的表面安装10只光纤光栅位移传感器

横向每隔2m安装一只

设置2个监测段

每段安装5只光纤光栅位移传感器。长期监测表明:重力墙在距离监测起始点0

18 m监测点处出现位移的变化较大

最大分别为0.86

0.99

0.69 mm。

Abstract

In process of mountain road operator

change of gravity wall displacement must be mastered. By finite element analysis on gravity walls determine monitoring region

10 fiber grating displacement sensors are mounted on the wall surface of the monitoring region

a lateral installation intervals of 2 m

two monitoring sections are set

each section is installed 5 fiber grating displacement sensors. Long-term monitoring show that gravity walls occurs a larger displacement changes 0

8 and 18 m away from monitor point

the biggest difference is 0. 86

0. 99

0. 69 mm.
