Description

technical field

[0001] The invention relates to a monitoring method of a distributed optical fiber monitoring device for hydraulic structure deformation, which belongs to the field of construction. Background technique

[0002] During the operation of hydraulic structures such as embankments and sluices, problems such as uneven settlement often occur, which adversely affect the safety and normal use of buildings, and even lead to building damage or accidents. By arranging monitoring instruments or devices, real-time acquisition of regional deformation information, reasonable analysis of regional deformation space and time variation rules, timely detection of abnormal regional deformation (especially uneven deformation), and scientifically taking preventive or control measures are necessary to ensure the protection of hydraulic structures. Material safety service is of great significance.

[0003] At present, conventional hydraulic structure deformation monitoring devices ha...
