成都市宜居水岸工程市级示范段生态化河堤行洪能力分析

Analysis on Flood Discharge Capacity of Ecological River Embankment for Municipal Demonstration Section of Chengdu City Livable Waterfront Project

成都市宜居水岸工程市级示范段主要涉及由中心城区南河、浣花溪、干河、西郊河四条河道组成的区域水网,汇流条件复杂。通过建立数学模型,模拟河岸生态化改造后的河道行洪情况。经分析表明,示范段生态化河堤行洪能力总体上可满足相应防洪标准,并对河堤生态化改造提出针对性意见。

The municipal demonstration section of Chengdu City Livable Waterfront Project mainly involves the areal water network composed of four rives of South River in the central urban area,Huanhua Creek,Ganhe River and West Suburb River.The confluence conditions are complex.The establishment of mathematical model simulates the flood discharge of rivers after the ecological reconstruction of river embankments.The analysis result shows that the flood discharge capacity of ecological embankment in the demonstration section can generally meet the corresponding flood control standard.This paper puts forward the targeted comments on the ecological reconstruction of river embankment.
