光纤传感器系统在土工结构的静动应变测量上的应用

Fiber optic sensor systems for static and dynamic strain measurements of geotechnical structures

评估了光纤传感器作为完整的结构部件在恶劣的环境条件下,进行长期或短期应变监测的可行性。不同的规模和材料的土工试验过程中已经使用了光纤传感器。实例研究包括静力轴向的钻孔桩测试、钻孔测斜、试验室的单轴压缩测试。

We assess the feasibility of fiber optic sensors as structurally integrated components for short and long-term strain monitoring under rough environmental conditions.Geotechnical testing procedures at different scales and in various materials have been carried out with these sensors.Case studies include a static axial borepile test,borehole inclinometer measurements,and uniaxial compression tests at laboratory scale.
