Design method for multi-point flexible displacement sensor

Abstract

A design method for a multi-point flexible displacement sensor, characterized in that the method comprises the following steps: designing a multi-point flexible displacement sensor structure, establishing a displacement sensing mathematical model of the sensor, carrying out a sensor calibration test, applying the calibrated sensor to soil shear deformation measurement. Compared with the prior art, the beneficial effects of the invention are as follows: The multi-point flexible displacement sensor designed in the invention has a small size and low flexural rigidity. After being embedded in soil, it can deform coordinately with the soil, effectively avoiding disturbance to the soil. In combination with a distributed monitoring network, multi-point synchronous monitoring is realized.
