零增地洪涝调蓄革新:建筑地下空间"平急两用"韧性体系构建
Innovative flood retention with zero land expansion:construction of a resilient dual-use system for underground space
摘要
Abstract
With the acceleration of urbanization and the increasing frequency of extreme rainfall events,traditional flood control facilities in high-density urban areas face contradictions between retention capacity and adaptability,making it difficult to meet the demands for rapid response and reliable defense.There is an urgent need to establish a resilient urban flood control system that can be rapidly deployed and structurally safe.This paper proposes the concept of a Flood-retention Building System(FBS),guided by the principle of"zero additional land use".Through a"space utilization+active regulation"mechanism,the system innovatively utilizes underground building space,converting foundation pit cushion cavities into"flood storage chambers",and switching basements into"flood storage tanks"during extreme weather events,thereby forming flood retention units within building boundaries.Supported by"overflow pressure control"active anti-buoyancy technology,FBS extends building structural functions through space utilization,enabling active regulation of urban waterlogging.By adopting a tiered flood retention strategy,it ensures efficient response to pluvial flooding during extreme rainfall.Operating under the three-phase model of"normal storage-pre-alert drainage-emergency flood diversion",and integrated with an IoT-based scheduling platform,the system realizes a distributed regional flood retention network.Calculation results show that a conventional 10 000 m2 two-level underground space retrofitted with FBS can provide about 5000 m3 of flood storage chambers and 100 000 m3 of flood storage tanks,while reducing construction costs to 10%of traditional systems.It is suggested that flood retention capacity be incorporated into regulatory planning as a mandatory indicator,supplemented by floor area ratio incentives and financial subsidies,to promote the wide application of FBS and support the high-quality development of resilient cities.关键词
