CRACK DETECTION METHOD FOR REINFORCED CONCRETE, AND CRACK DETECTION SYSTEM FOR REINFORCED CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a crack detection method for a reinforced concrete structure and a crack detection system for a reinforced concrete structure, in which micro cracks can be detected.SOLUTION: A crack detection system for a reinforced concrete structure includes: a measuring apparatus 1 which is mounted on CP100 and measures changes in distance between two points on the CP100 surface; a heater 2 for heating CP100; and a determination device 3 which determines whether or not cracks exist in CP100 based on changes in the distance between two points on the CP100 surface measured by the measuring apparatus 1.SELECTED DRAWING: Figure 1
