Abstract

ACCORDING TO THE NEED OF CABLE FORCE MONITORING OF SPACE CABLE STRUCTURE, A NEW FIBER BRAGG GRATING MONITORING METHOD IS PROPOSED BY ANALYZING THE MECHANISM, ADVANTAGES AND DISADVANTAGES AND APPLICATION SCOPE OF EXISTING CABLE FORCE MONITORING METHODS. THE RESULTS OF PRACTICAL ENGINEERING SHOW THAT: THE MECHANISM OF THIS METHOD IS CLEAR AND EASY TO IMPLEMENT; THE ADVANTAGES OF CLAMP CABLE, TENSION METER, AND JACK MONITORING METHOD ARE FULLY USED TO AVOID THEIR DISADVANTAGES; IN THE MUTUAL CHECK STAGE OF JACK AND CLAMP CABLE TENSION METER, THE MONITORING DATA ERROR OF THE TWO TESTING METHODS IS LESS THAN 5%, WHICH INDICATES THAT THE CLAMP STRAIN GAUGE IS ACCURATE AND EFFECTIVE; THIS METHOD HAS LITTLE INFLUENCE ON CONSTRUCTION, AND CAN MAKE FULL USE OF THE ENGINEERING PROJECT THE CLAMP CABLE TENSION METER IS ARRANGED IN THE PROCESS OF CABLE TENSION IN STAGES, WHICH CAN REALIZE THE IMPLEMENTATION WITHOUT AFFECTING THE ORIGINAL CONSTRUCTION PROCESS. IT PROVIDES AN EXPERIENCE REFERENCE FOR SIMILAR CABLE TENSION PROCESS AND CABLE FORCE CONTROL IN SERVICE STAGE IN THE FUTURE.
