【摘要】天津市中心城区内涝灾害频发,为减缓城市内涝灾害威胁,提出利用工程和非工程相结合的方法减缓城市内涝。在工程措施改造时,首先,加快海绵城市和城市双修建设,从大中小3个尺度对城市开敞空间改造,建设城市蓄水及渗水空间,从源头控制排水量,减缓城市径流;建设完善的排水管网、划定合理排水分区、提高城市排水标准、设置单向排水出口,建设水闸及排水泵站,实现强降雨时期快速排水。在非工程措施方面,利用大数据和互联网技术建设城市内涝预测平台和内涝服务平台,增加对城市积水点的预测水平,同时提高公众参与水平,实现强降雨时期全民参与城市内涝信息发布中,管理部门快速对内涝积水点快速进行控制,最后依托智慧城市建设,加强城市综合防灾平台建设和城市应急防灾平台建设,通过对各项排水设施和部门的智慧化控制,加强各部门之间的数据共享,及时进行应急策略的制定,减缓城市内涝发生。

【Abstract】There are frequent disasters in the downtown of Tianjin. It is proposed to use engineering and non-engineering methods to mitigate urban shackles. As for engineering measures, we should accelerate the construction of “sponge city” and “ecological rehabilitation and patchwork urbanism” to transform the open space from small, medium, and large scale, build urban water storage and seepage space to contain the drainage from the source, and slow down urban runoff. We should construct a perfect drainage pipe network and delimit reasonable drainage zones, improve urban drainage standards and set up one-way drainage outlets, build river gates and drainage pumping stations, and achieve rapid drainage during heavy rainfall. With respect to non-engineering measures, we should use big data and Internet technologies to build urban waterlogging prediction and service platforms, increase the forecast level of urban water accumulation points and the level of public participation, and realize the participation of all people in the city during heavy rainfall. The management also quickly controls the inflowing water points. Finally, we should rely on the construction of smart cities, strengthen the construction of a comprehensive disaster prevention platform and construct an emergency disaster prevention platform in the city by the intelligent control of various drainage facilities and departments. At the same time, we should enhance the exchange of data among different departments and draft the emergency strategies timely. In these ways, we can finally mitigate the waterlogging in the city.
