基于遥感技术的明珠湾亭角地区道路工程度汛排水方案
Scheme of flood-season drainage for road engineering in Tingjiao Area of Mingzhu Bay based on remote sensing technology
摘要
Abstract
Taking the Tingjiao area of Mingzhu Bay in Nansha District,Guangzhou,as a case,this study attempts to identify waterlogging risk areas under typical rainfall events using remote sensing technology and,on this basis,to develop corre-sponding drainage schemes for road engineering.Multi-temporal remote sensing images were used to retrieve surface water information,based on which a waterlogging frequency index was constructed and coupled with rainfall accumulation analysis to identify high-risk waterlogging areas.Subsequently,drainage schemes were proposed for representative roads within the study area.The results indicate that waterlogging risk is mainly concentrated on the western side of Jiancai Road in the northwestern corner of the study area,residential areas adjacent to Jiancai Road,and the zone between the eastern side of Gongye Road and Guiheng Stream.Under the combined effects of existing drainage facilities and pumping measures,water accumulated on Binjiang North Road,Planned Road 1,and Planned Road 2 can be completely drained within 1.06～1.84 h using four pumps(260 m3/h per pump),provided that the maximum water depth does not exceed 1.0 m.This study demon-strates that the integrated analysis of remotely sensed waterlogging frequency and rainfall accumulation can effectively sup-port the formulation of flood-season drainage schemes for urban road engineering,and can provide a technical reference for urban construction and flood drainage design in low-lying,waterlogging-prone areas.关键词
