본 연구에서는 상습침수구역이자 산지 도시지역인 강원도 평창군 하진부지구에 XP-SWMM모형을적용하여 빈도별 내수재해를 모의하고 원인 분석 및 내수재해 해소방안을 제시하였다. 강원도 평창군 하진부지구에 침수해석을 모의한 결과 방재성능목표 강우량뿐만 아니라 저빈도 강우사상에서도중⋅하류 관로에서 월류가 발생한 것으로 나타났다. 이러한 내수재해를 저감하기 위해 우수관로개선방안과 배수펌프장 신설 방안에 대해 모의하였으며 적합한 해소방안을 제시하였다. 우수관로개선에 따른 모의결과 침수면적은 54%가 저감되고, 침수심은 26%가 저감된 것으로 나타났으나 우수관로 개선만으로는 중⋅하류에 발생하는 월류를 해소하기 어려움이 있어 추가 방재시설물을 설치해야 할 것으로 나타났다. 이에 우수관거 개선 및 배수펌프장 신설을 모의한 결과 목표 저감량 전량을 해소할 수 있는 것으로 나타났다. 본 연구는 내수재해를 저감하기 위한 치수계획 수립 시 기초자료로 활용될 것으로 판단된다.
Abstract
In this study, the XP-SWMM model was applied to Hajin-bu district in Pyeongchang-gun, Gangwon-do, which is a habitual inundation zone and mountainous area, and the inundation disasters were simulated by frequency and the cause analysis and the solution of domestic disasters were suggested. As a result of simulating inundation analysis in the Hajin district of Pyeongchang-gun, Gangwon-do, it was found that overflow occurred in the middle and down stream pipeline as well as the rainfall target for disaster prevention performance. In order to reduce the inundation disaster, the improvement plan of the rainwater pipeline and the new drainage pumping station were simulated and appropriate solutions were presented. As a result of simulations following improvement of rainwater pipeline, the inundation area was reduced by 54% and the inundation depth was reduced by 26%. However, it was found that improvement of rainwater pipeline alone had difficulty in solving the overflow in the middle and downstream. As a result of simulating the improvement of rainwater pipeline and the establishment of a drainage pumping station, it was found that the total amount of target reduction can be solved.
