dc.description.abstract | Criteria for rehabilitation priority are discussed to evaluate structural stability of deteriorated water transport and transmission pipes, in this study.For the purposes, safety factor is introduced and estimated by measuring tensile strength and by analyzing stress caused by the internal-external loads working on buried pipe body. Related informations are surveyed and collected under various conditions in the fields by digging out and the structural stability is assessed.In the evaluation results of structural safety, it is shown that steel pipe is more affected by external load than internal load.The average external load is estimated as 53.7 ㎏/㎠ and total hoop stress is estimated by 2676.5 ㎏/㎠. Also, Poisson effect into longitudinal direction due to internal and external loads is most influential on hoop stress.The calculated safety factors of hoop stress are ranged from 0.7 to 5.2 with average value of 2.1, considering a bending stress to longitudinal direction.The decision of rehabilitation priority by safety factors show that structural safety of CIP sample 1(S1) was assessed at the lowest order with safety factor value, 0.7 and that of DI sample 15(S15) was evaluated as the most stable in structural aspect. | - |
