Deterioration of the presence or absence of reinforced concrete pipes are checked and the deterioration progress level is classified and based on the inspection result, a portion to be inspected in detail in an inspection area is selected. With respect to the selected portion to be inspected in detail, the pipe thickness and the diameter of reinforcing bars are measured and the location of reinforcing bars in the portion to be inspected in detail are checked. Using the data of thickness of a pipe, diameter reinforcing bar and disposition of reinforcing bars, structural analysis is carried out and the strength of a pipe of the reinforced concrete pipe is calculated. The calculation result is used as information for evaluating the deterioration state of the reinforced concrete pipe. <IMAGE> |
