为研究上海五角场区域地下民防工程对城市内涝积水的防御能力，本文建立了内涝模型，计算得出了该区域在不同降雨重现期下的积水范围和深度，并对区域内50个民防站点在不同降雨重现期下的内涝进水情况进行了分析.结果表明，城市地下空间的进水重现期除受自身的高程、高差影响外，还与周围地势和排水条件密切相关.不考虑安全余量的情况下，五角场区域民防站点进水重现期普遍较高.随着安全余量的增加，民防站点进水重现期普遍有所下降，不同站点对安全余量增加的敏感程度有一定差异.
In order to evaluate the defense capability of civil defense projects around the Shanghai Pentangle Square under urban local flooding, an urban local flooding model was built to determine the inundated areas and water depth under different rainfall return periods, and the pluvial flooding risk map was achieved. The inundated return periods of the 50 civil defense projects around the study area were calculated. The results showed that the inundated return period was connected not only with the elevation difference but also the topography and drainage condition. The inundated return periods were generally high and decreased as the freeboard increasing, but they showed different sensitivities to the increased freeboard.
