Abstract:In order to solve the problem of waterlogging in the metro stations because of extreme weather, the anti-waterlogging measures for the gateways in the stages of planning, design, construction and operation are systematically studied. The basic anti-waterlogging measure system is formed by planning and considering the site selection, designing the multi-line defenses, and constructing the temporary measures in place to achieve the effects of anti-waterlogging capacity before the operation stage, waterlogging reduction capacity in the matter and recovery capacity afterwards. The design concept of sponge city is introduced to the comprehensive anti-waterlogging system for the gateways of sponge city metro stations. The measures of grass planting ditch, permeable pavement and low elevation greenbelt are taken to decrease the surface runoff, reduce the risk of waterlogging, and minimize the impact of station gateways on the urban ecological environment to some extent.
