特大洪涝场景下地表-地下耦合模拟研究
Research on surface-underground coupling simulation under heavy flood scenarios
摘要
Abstract
Urban flooding can lead to severe waterlogging,threatening the safety of both surface and un-derground spaces.Current research on urban waterlogging often neglects the simulation of underground space flooding and the interaction between underground and surface waterlogging.This study took a typi-cal area in Beijing as a case,where a hydrodynamic model incorporating underground flooding was devel-oped to simulate the"23·7"extreme rainfall event in Fangshan District.The impact of underground space flooding on surface waterlogging was analyzed and compared.The results showed that the extreme flood event would induce high risks in certain areas of the study region due to water depth,velocity,and waterlogging;underground flooding could mitigate surface flooding risks.In this scenario,the high-risk areas associated with underground flooding were 63.18％lower than those in the traditional scenario Flexi-ble adjustments to the defense height of underground spaces were necessary to achieve the objective of minimizing overall waterlogging risks for both surface and underground areas.The findings provide a valu-able reference for urban waterlogging risk assessment and flood control measures.关键词
