Abstract:
A damaged sewer pipe is considered a major cause of the occurrence of urban ground cave-ins. Identifying the sewer pipe characteristics that contribute to the occurrence of ground cave-ins can be highly helpful in detecting the damaged sewer pipes and preventing ground cave-ins. To achieve this aim, Student’s t-test and chi-square test were performed with all the sewer pipes in Seoul that included the ground cave-in occurrence and nonoccurrence cases.
