최신판례분석 : 선택적 병합청구에 있어서의 일부승소판결 - 대법원 2016. 5. 19. 선고 2009다66549 전원합의체 판결 -

권혁재1 ( Kwon Hyuk Jae ) 법조협회 2016 法曹 Vol.65 No.7

판례는 선택적으로 병합청구 된 각 청구권에 대하여 소송물로서의 독자성과 상호경합을 인정하고 있다. 그 결과 법원이 원고에게 가장 유리한 어느 한 청구권을 선택하여 인용한다고 하더라도 그 인용된 급부가 원고의 청구 범위에 미치지 못할 때에는 나머지 병합청구 전부에 대하여 심리·판단할 것을 요구하고 있다. 이와 같은 결론은 선택적 병합제도의 본질적 특성과 제도적 장점을 훼손할 수 있다. 선택적 병합청구의 제도적 장점을 살리려면 원고가 청구취지에서 구하고 있는 급부 자체에 중점을 두고법원은 가장 유리한 청구를 기초로 판결하도록 의무화하고, 그것으로써 나머지 병합청구에 대한 심리·판단이 함께 이루어졌다고 보는 것이 타당하다. 원고가 선택적 병합청구를 하고 있더라도 법원의 석명권행사를 통하여 예비적 청구로 변경하도록 하는 것도 필요하다. In case of selective consolidation of claims, the precedent of Korean Supreme Court acknowledges independence and mutual coexistence about each claim as subject matter of litigation. As a result, even if the court select and allow the most favorable one of those claims to the plaintiff, the court should hear and decide residual consolidation of claims all, in case allowed payment is not sufficient to the amounts of the plaintiff. These conclusion might damage essential property and merit of selective consolidation of claims. In order to bring the merit of selective consolidation of claims to life, it is necessary to make mandatory to adjudicate on the basis of the most favorable claim. By doing so, hearing and decision could come to a close about residual consolidation of claims. In conclusion, this result is helpful to solve problem at one try.

Reduced thickness of the water pipes due to corrosion makes it difficult to perform the original functions since corrosion in metallic water pipes can occur over time. In this study, reliability model that can estimate the probability of pipe breakage is developed regarding corrosion depth increment according to service year. Probability of pipe breakage was calculated by FORM(First Order Reliability Method) and unsteady analysis was performed to analyze the statistical properties of water pressure. And KCIP(Korea Cast Iron Pipe) equation was adopted for the reliability function. Furthermore, change of pipe thickness was estimated by Nahal and Khelif equation and Romanoff equation. Therefore, pipe thickness was calculated due to change of corrosion depth and probability of pipe breakage was calculated and compared with 10, 20, 30 service years. From the results, probability of pipe breakage for network A is gradually increased from 6.8% to 8.6% according to service year of 10, 20, 30 when Nahal and Khelif equation is applied. And probability of pipe breakage for network A is also gradually increased from 6.4% to 8.9% according to service year of 10, 20, 30 when Romanoff equation is applied. 상수도관은 시간이 흐름에 따라 부식이 발생할 수 있으며 이로 인해 관두께가 작아져 기존의 성능을 발휘하기 힘들어진다. 이에 본 연구에서는 관두께 변화에 따른 파괴확률을 정량적으로 산정할 수 있는 수치모형을 개발하였으며 이를 실제 상수도관망에 적용하여 사용연수가 증가함에 따라 파괴확률이 어떻게 변화하는지 분석하였다. 파괴확률은 FORM(First Order Reliability Method)를 사용하여 산정되었고 압력의 통계적 특성을 분석하기 위해 여러 가지 다른 시나리오를 이용하여 부정류해석을 수행하였으며 신뢰함수로는 주장력공식을 개선한 KCIP(Korea Cast Iron Pipe)식을 사용하였다. 또한 부식으로 인한 두께변화를 산정하기 위하여 Nahal and Khelif식과 Romanoff의 식을 사용하였으며 이를 통하여 10년, 20년, 30년 후의 부식으로 인한 관두께를 추정하였고 이에 따른 파괴확률을 산정하여 비교분석하였다. 본 연구에서 적용된 상수도관망A의 경우 Nahal and Khelif의 식을 사용하였을 때 100 mm 직경의 강관이 사용연수가 10년, 20년, 30년으로 증가할 경우 파괴확률은 상수도압 $12kg/cm^2$ 일 때 각각 6.8%, 7.8%, 8.5%로 점진적으로 증가하는 것을 알 수 있었고, Romanoff의 식을 사용하였을 경우 6.4%, 7.5%, 8.9%로 증가하는 것을 확인하였다.

권혁재,Kwon,Hyuk Jae 한국방재학회 2013 한국방재학회논문집 Vol.13 No.5

본 연구에서는 상수관망의 최적의 수압모니터링지점 선정방법을 제시하고 이를 모의하기 위해 구축된 파일럿플랜트에 적용한 실험결과와 비교분석하였다. 모니터링 지점선정방법은 압력기여도분석과 민감도분석으로 구분하여 계산하였다. 각 절점마다 일정한 유량을 필요유량에 합산하여 유량에 변화를 주었으며 이로 인한 다른 나머지 모든 절점의 압력변위를 계산하였다. 이렇게 계산된 결과는 어느 절점에서의 유량변화가 나머지 절점에 어느 정도의 압력변위를 발생시키는지 확인하는 방법으로써 압력기여도와 필요유량변화로 인한 압력의 민감도 분석을 통하여 지점을 선정하였다. 또한 파일럿플랜트에서 실험을 통하여 압력기여도분석결과와 민감도분석결과와 비교하였다. 누수를 실제 재현하고 여러 절점에서의 압력변위를 측정하여 그 결과를 바탕으로 모니터링 지점선정방법을 비교하였다. 네 개의 압력센서를 이용하여 다섯 번 압력센서의 설치위치를 변경하면서 누수에 대한 압력변위를 측정하였다. 실험결과 두 가지 해석방법이 모두 수압모니터링 지점선정방법으로 적합함을 확인할 수 있었다. In this study, determination method of pressure monitoring location in water distribution system was suggested and applied to the pilot plant for the experimental verification. Monitoring location was estimated by two methods such as pressure contribution analysis and pressure sensitivity analysis. Pressure change due to change of demand was calculated for each junctions. Results of the calculation were used to determine which junction has high pressure sensitivity and pressure contribution to another junctions. Furthermore, results of analysis were compared with the results of experiment. Real leakage was reproduced and pressure change was measured in pilot plant. Pressure change was measured by four pressurer sensors with five different sensor locations. From the results, it was found that the results of determination methods of monitoring location are well matched with the results of experiment.

본 연구에서는 우수관의 조도계수의 변화에 따른 성능불능확률을 산정할 수 있는 신뢰성 모형이 개발되었다. 조도계수는 우수관의 토사의 적체에 따라 다시 산정되었으며 새로운 조도계수를 이용하여 신뢰성 해석이 수행되었다. 해석결과, 우수관에 적체되는 토사의 깊이가 증가함에 따라 우수관의 용량은 크게 감소하고 성능불능확률은 크게 증가함을 알 수 있었다. 본 연구에서는 우수관에 적체되는 토사의 깊이에 따라 산정된 조도계수를 사용한 신뢰성 모형을 대구와 전주에 적용하였다. 원형 우수관에 적체된 토사의 깊이가 증가할수록 우수관의 조도계수는 커지고 성능불능확률도 역시 크게 증가 하는 것을 알 수 있었다. Reliability model which can calculate the probability of performance failure of storm sewer was developed considering change of roughness coefficient in this study. Roughness coefficient should be re-evaluated due to accumulations of debris in sewer pipe. Therefore, roughness coefficient according to depth of debris in circular sewer pipe was determined for the present study. Reliability analysis was performed with the new roughness coefficient. After the analysis, it was found that capacity of storm sewer can be significantly decreased and probability of performance failure of storm sewer can be significantly increased by increasing the depth of debris in storm sewer. In this study, reliability model was applied for the Daegu and Jeonju using new roughness coefficient which was determined according to accumulation of debris in circular storm sewer. It was observed that if the depth of debris is increased, roughness coefficient is increased simultaneously and probability of performance failure of storm sewer is significantly increased.
