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.
