光纤Bragg光栅在公路软基沉降监测中的应用
Fiber Bragg grating monitoring technology applied in soft ground settlement of highway
摘要
Abstract
The fiber Bragg grating (FBG) technology was studied based on the current monitoring status of the highway soft ground settlement, such as the low degree of automation, the unsatisfied accuracy of the device, the slow data transmission and the greater measurement errors.The development of the long range optical fiber displacement sensor as well as its burying techniques which are suitable for soft ground settlement monitoring was analyzed.Both of them were applied in Dechang Highway D10 subject.The results show that the long-range optical fiber displacement sensor is able to meet the requirements of the soft ground monitoring.And data can be accurately monitored by means of real-time or on-line continuously.关键词
