摘要

在简述了光纤Bragg光栅传感器基本工作原理的基础上，通过沪―蓉―西高速公路龙潭隧道支护锚杆轴力监测的工程应用，探讨研究了光纤传感技术用于岩土工程监测的几个重要环节——传感器选择、传感器安装、传感器标定及传感器埋设。通过现场监测获得了复杂地质条件下特长隧道支护锚杆轴力的变化特性，为光纤传感技术在岩土工程监测领域的应用积累了一定的经验。

Abstract

The basic principle of fiber Bragg grating sensor is described. Through engineering application of fiber Bragg grating sensor to monitoring axial forces of anchor bolts for Longtan tunnel of Hu-Rong Expressway West Section

some important aspects of fiber optical sensing technology applications to geotechnical engineering monitoring

which are selection of sensors

installation of sensors

calibration of sensors and embedding of sensors

et al

are discussed. Through local monitoring

the characteristics of axial forces of anchor bolts are obtained. And some useful experiences with application of fiber optical sensing technology to geotechnical engineering are summarized.
