•A joint fiber-optic displacement sensor base on OFDR and shear lag model is proposed.•Monitoring errors caused by strain transfer are considered.•The feasibility and effectiveness of the sensor are verified in the test. Landslide displacement monitoring is an efficient method to mitigate casualties...
