    摘要:

    为探究极端暴雨下城市基础设施洪涝致灾规律,以西安某新建330 kV变电站为例,构建基于GPU加速技术的二维地表水动力城市雨洪过程模型,对不同降雨条件下变电站站区积涝过程进行模拟,对比分析不同降雨与站区水位的响应关系。结果表明:①站区水位随降雨持续先增加,后逐渐缓慢降低;②随着设计暴雨重现期增加,站区内的最高水位不断增高,在300 a一遇降雨重现期下趋于稳定,P≤300时水位增加量占整体的74.31%;③重现期 300 a一遇为水位增长量拐点,建议根据行业特色、经济性、所在汇水区的产汇流状况和洪涝致灾风险等因素综合考虑设防水平。研究揭示了极端降雨对变电站设计标高的量化规律,为极端暴雨下变电站及城市其他新建基础设施的防洪建设提供重要参考。

    Abstract:

    Aiming to investigate the flood disaster patterns of urban infrastructure under extreme rain storms, a two-dimensional GPU-accelerated surface water flow and transport model (GAST) was con structed for a newly built 330 kV substation in Xi'an. The model was used to simulate the flooding pro cess in the substation area under different rainfall conditions and to compare and analyze the response of the station area's water levels to different rainfall intensities.. The results indicated that: ① The wa ter level in the substation area initially increased with the duration of the rainfall and then gradually de creased. ② As the design rainstorm return period increased, the highest water level in the substation area also increased, gradually stabilizing at the 300-year return period (P). When P≤300, the increase in water level accounted for 74.31% of the total. ③ The 300-year return period was the inflection point for the water level increase. It was recommended to consider various factors including industry characteristics, economic feasibility, watershed runoff conditions, and flood risk when determining the flood defense level. The study elucidates the quantitative relationship of extreme rainfall on the de sign elevation of substations and provides important reference for flood control in substations and other new urban infrastructure under extreme rainstorms.
