Method for arranging distributed type optical fiber sensor

The invention relates to a method for arranging a distributed type optical fiber sensor, and belongs to the technical field of road detection. The method solves the problems that when a sensor is distributed on a bituminous pavement at present, the construction period is long, the slotting difficulty is large, the sensor fixing effect is poor, and the backfilling effect is difficult to guarantee.The method comprises the following steps that A, fixed seats for limiting axial movement are arranged on the two ends of the existing distributed type optical fiber sensor, and the surface of the distributed type optical fiber sensor is coated with a thermoplastic colloidal material; B, slots are formed in the existing pavement, notches in the two ends of the slotted pavement are enlarged to ensure that the fixed seats are smoothly installed into the slots in the pavement; and C, the mounted fixed seats are fixed in the slots in the pavement, a mixed high-temperature asphalt mixture is packedinto the slots in the pave
