摘要:- 現(xiàn)今大多數(shù)城市建成區(qū)雨水管網(wǎng)存在設(shè)計(jì)標(biāo)準(zhǔn)偏低、源頭控制徑流能力低等問題，使得內(nèi)澇風(fēng)險(xiǎn)增加。以某平原水網(wǎng)城市為例，采用地理信息系統(tǒng)（GIS）技術(shù)與綜合流域排水系統(tǒng)模型InfoWorks ICM相結(jié)合的方法，對(duì)不同降雨重現(xiàn)期進(jìn)行情景模擬，分析評(píng)估內(nèi)澇風(fēng)險(xiǎn)，并通過對(duì)模擬結(jié)果進(jìn)行水量平衡分析，得出需要通過增設(shè)源頭LID設(shè)施、管道提標(biāo)改造、合理布置外圍排澇設(shè)施等措施有針對(duì)性地預(yù)防內(nèi)澇發(fā)生、降低內(nèi)澇風(fēng)險(xiǎn)。
Abstract:- At present, problems of low design standard and low source control capacity exist in storm pipe network in most urban built- up areas, which increases the risk of waterlogging. Taking a plain river network city for eample, the geographic information system (GIS) technology combined with integrated catchment drainage system model InfoWorks ICM were applied to simulate scenarios at different rainfall return periods,the urban waterlogging risk was analyzed and assessed, and water balance analysis was carried out on the simulation results. It was concluded that measures should be taken to prevent the occurrence of waterlogging and reduce the risk of waterlogging by adding LID facilities at the source, upgrading pipelines, and reasonably arranging peripheral drainage facilities.
