SYSTEM FOR MEASURING AMOUNT OF MOVEMENT OF MOVABLE SUPPORT FOR BRIDGE

摘要

PURPOSE: A system for measuring the movement distance of a movable support for a bridge is provided to enable the comparing analysis of the movement of a bridge based on temperature change due to season change. CONSTITUTION: A system(100) for measuring the movement distance of a movable support for a bridge comprises movable supports(130), optical fiber brig grating sensors(140), jigs, an optical fiber cable(150), and a terminal box(170). The movement distance of the movable support for a bridge is measured on the top of the bridge at the same time. The optical connector is accepted in the terminal box.
