摘　　要：提出一种基于新型测斜管和FBG倾角传感器的新型分布式测斜方法。该方法采用柔性变形管与PVC刚性管相连接的改进型测斜管,选取具有增敏结构的新型FBG倾角传感器作为分布式测斜装置的高精度传感器,并利用光纤光栅温度传感器作为温度补偿传感器。在边坡抗滑桩中的实际应用结果表明,基于FBG倾角传感器的新型分布式测斜技术在工程应用中具有有效性,并可成功解决测量中的温度补偿问题。In order to resolve the error of traditional FBG measurement, a new distributed inclination method that is based on new-type inclination tube and fiber Bragg grating （FBG） tilt sensor is pro- posed. The method uses improved inclination tube whose flexible deformation tube is connected to the PVC rigid tube. A new FBG tilt sensor with enhanced sensitivity structure is chosen as the high preci- sion tilt sensor of the distributed inclination technology, and the fiber grating temperature sensor is used as the temperature compensation sensor. The application of the technology in the slope anti-slid- ing pile shows that this FBG inclination sensor-based technology is feasible and effective in engineer- ing, and can successfully solve the problem of temperature compensation in the measurement.
