摘要
阐明了光纤测试技术相对于传统岩土工程测试技术的优点,简要介绍了两种典型光纤传感器——Fabry- Prot光纤传感器和Bragg光栅传感器的工作原理,通过试验证明了其可靠性,并通过国内外几个工程实例说明了光纤传感器的主要用途。
The working principles of both Fabry-Prot cavity type and Bragg grating type of fiber optic sensors in geotechnical engineering monitoring are introduced. Their advantages are illustrated comparing to traditional electric and mechanical sensors. The test results from laboratory and field show the reliability and wide usage of fiber optical sensors.
