摘要:
针对福建省龙岩市连城县近年来遭遇的特大暴雨洪涝灾害问题进行了成因分析，识别出三方面九大类原因，进而提出了“上截、中蓄、下排”的系统应对措施及规划方案，包括流域洪涝统筹应尽量避免山洪侵入城区，加强内河、管渠和外河在水位标高、排水能力方面的衔接；新建区域应加强建设管控，以排水为导向，进行竖向设计和组织；结合竖向控制布局，对可作为排涝通道的现状水系予以保留，并结合低洼地区建设“干湿皆宜”的调蓄空间；结合受纳水体的位置，合理划设非主干道路作为超标径流行泄通道；重点区域排涝应通过“一点（片）一策”结合雨水管渠改造提出建设方案，以期为东南沿海丘陵型县城构建韧性排水防涝体系提供参考。
Abstract:
The cause of rainstorm floods in Liancheng County of Longyan City, Fujian Province was analyzed. Three aspects of nine kinds of reasons were identified and the system response and planning scheme of “upper interception, middle storage and lower discharge” was proposed. The overall planning of floods in the river basin should avoid the intrusion of flash floods into the city. The connection of water level elevation and drainage capacity between inland rivers, pipe channels and outer rivers should be strenthened. New area of the city should strengthen the construction control, drainage oriented, vertical design and organization. The current water system that can be used as the drainage channel should be retained combined with the vertical control layout, and the low?lying areas should be built with “dry and wet” regulation and storage space. Considering the location of the receiving body, the non?main road is reasonably designated as the discharge channel of excessive runoff. The construction scheme for waterlogging drainage in critical areas should be put forward through “one point (area) one policy” combined with stormwater pipe and canal reconstruction. This paper endeavored to provide references for the construction of resilient drainage waterlogging control system in southeast coastal hilly Counties.
