摘要
Abstract
Due to the unique geographic location of the Pearl river estuary,bridge and gate structures are often built in close proximity,requiring comprehensive consideration of their impact on water conservancy and urban transportation.This study utilized a large-scale 1D-2D coupled hydrodynamic model encompassing the Pearl river delta river network and outer estuary to provide boundary conditions for a local 2D model built with MIKE21.The Lingxin avenue southern extension project in Nansha district,Guangzhou,including the Shijiuyong bridge and East sluice gate,was taken as the case study.Hydrodynamic changes before and after construction under different scenarios were simulated.Comparative analysis of design alternatives supported a separated structure solution-placing bridge piers within the gate wing walls-to minimize overall hydraulic impacts.The model demonstrated strong adaptability to estuarine hydrological variations and can accurately predict the impact of bridge-gate co-construction,offering a robust technical basis for flood impact assessments.关键词
