【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。
