In this paper, t he working mechanism of flexible pipe was int roduced, and the construction measure of Grooving method was proposed.T he rationale of the const ruct ion measure was explained, and then the feasibility of the measure was verified through the field tests for H DPE w inding reinforcement pipe. Based on the deformation values measured by the slide resistance displacement sensor and the strain dat a measured by the fiber grating, the deformation and st rain of
