| description | Based on the two methods of the index system and the scenario simulation, hazard assessment of urban waterlogging disaster on underground substations in Shanghai was carried out. The results show that: (1) the return period rainfall of underground substations in Shanghai gradually increases with the extension of the return period; in terms of spatial distribution, the return period precipitation of the stations along the river and within the inner ring is higher than that of the stations outside the inner ring. (2) The waterlogging thresholds of stations between the inner ring and the middle ring are highest. The waterlogging thresholds of stations within the inner ring and between the middle ring and the outer ring are higher than those in the suburban stations. (3) Under the 20-year return period extreme precipitation scenario, the urban waterlogging risks of underground substations in Shanghai are mainly at low and medium levels. Under the 50-year and longer return period extreme precipitation scenario, the risks of inner ring stations increase to medium-high level. |
