碩士 === 正修科技大學 === 營建工程研究所 === 107 === In recent years, due to climate change, the frequency of extreme rainfall has increased and 78% of annual rainfall in Taiwan is from May to October. Because of the uneven distribution of time and space of rainfall, the intensity varies greatly. Therefore, roads, slopes and bridges are often destroyed during the rainy season. It pays much attention to the efficiency of repair and rejuvenation for the damaged repair projectand the repair task must be completed as scheduled. Therefore, this article will take three road box culvert damage repair projects caused by typhoon or heavy rain as an example. Through case collection and analysis, it proposed better construction procedures and recommendations. In addition, the SWMM mode is used as an analysis tool to compare the simple hydrologic analysis mode established in this paper. From the analysis results, it could be seen that the simple hydrologic analysis model established in this paper could provide reference for the rapid disaster recovery project planning in the event of future disasters. 【Keywords】：Box culvert, SWMM, hydrologic analysis
