DAMAGE SENSING SYSTEM AND METHOD FOR DOUBLE WATER BARRIER SHEET, AND WATER STORAGE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a damage sensing system and method which can sense damage of a double water barrier sheet, and at the same time, detect whether either an upper water barrier sheet or a lower water barrier sheet is damaged.;SOLUTION: The damage sensing system 12 installed in a waste disposal site 10 comprises an optical fiber cable 13 installed in the double water barrier sheet 18 for measuring temperature distribution in the double water barrier sheet 18, a well-known temperature measuring means 22 for measuring temperature distribution of positions along the optical fiber cable 13, and an alarm device 24 giving a warning by light, sound, or the like when a degree of change in the temperature distribution in the double water barrier sheet 18 becomes larger than a predetermined degree.;COPYRIGHT: (C)2009,JPO&INPIT
