基于GIS与SWMM的暴雨内涝风险评价——以山东半岛某LNG接收站为例

Risk Assessment of Rainstorm Waterlogging Based on GIS and SWMM—A Case Study of Shandong Peninsula LNG Receiving Station

摘要: 随着全球变暖和厄尔尼诺事件回归导致极端天气频发，洪涝灾害频次和程度逐步上升。暴雨内涝风险评价逐渐成为城市防灾减灾工作的重点。本文基于GIS和SWMM构建了山东半岛LNG接收站暴雨内涝模型，采用50 mm、100 mm、200 mm、400 mm四种降雨情景，对山东半岛某LNG接收站开展暴雨内涝模拟分析及风险评价。根据评价结果提出山东半岛LNG接收站站暴雨内涝预警及治理措施。研究思路对于国内同类型LNG接收站开展暴雨内涝风险防范工作具有借鉴意义，研究结果可供山东半岛LNG接收站暴雨内涝风险应对参考。

Abstract: With the return of global warming and El Niño events, extreme weather events have become more frequent, and the frequency and severity of floods have gradually increased. Rainstorm waterlogging risk assessment has gradually become the focus of urban disaster prevention and reduction. In this paper, based on GIS and SWMM, a rainstorm waterlogging model of Shandong Peninsula LNG Terminal is constructed. Four rainfall scenarios of 50 mm, 100 mm, 200 mm and 400 mm are used to carry out simulation analysis and risk assessment on rainstorm waterlogging of Shandong Peninsula LNG Terminal. According to the evaluation results, the early warning and control measures for rainstorm and waterlogging in Qingdao LNG Terminal are proposed. The research idea has reference significance for domestic LNG terminals of the same type to carry out rainstorm waterlogging risk prevention work, and the research results can provide reference for rainstorm waterlogging risk response of Shandong Peninsula LNG terminals.
