Abstract

This study (II) has appled the new assessment model of large-diameter pipe deterioration proposed by the study (I) to the metropolitan multi-regional water supply system (1st phase). In the total 30 pipelines, 24 and 27 pipelines were required for improvement as results from the existing evaluation methods 1995 and 2002, respectively. The assessment results were almost similar in the new developed model and the existing methods. It is founded that the new simple model developed in this study can produce reliable results, consistent with those from the existing methods requiring many factors for a pipe deterioration assessment. It is therefore expected that the new model would be helpful in practical applications of a pipe deterioration assessment since it can save both temporal and economic costs for experiments and analysis, as compared with existing assessment methods.

본 연구(II)는 연구(I)에서 제안한 대구경 관로의 노후도 평가 모형을 수도권 광역상수도 1단계를 대상으로 이를 적용하였다. 노후도 평가 방법별 적용 결과에서, 총 30개 관로 중에서 1995년 평가방법은 24개, 2002년 평가방법은 27개 관로가 개량이 필요한 것으로 나타났다. 또한 개발된 모형과 기존의 2개 평가방법의 결과는 거의 일치하는 것으로 산정되었다. 즉, 본 연구에서 개발한 간편모형은 기존의 많은 인자를 이용하여 노후도를 평가하는 방법과 비교에서 신뢰할 수 있는 부합되는 결과를 보여 주었다. 따라서, 본 연구에서 개발한 모형은 기존의 노후관 평가방법과 비교시 실험 및 분석 등에 필요한 시간적 경제적 비용을 절약할 수 있어 실무적 적용에 많은 도움을 줄 수 있으리라 기대된다.
