【摘要】：隨著我國城市化進(jìn)程的加劇,區(qū)域生態(tài)水文平衡被破壞,城市發(fā)展過程中需要面對城市缺水與雨水流失問題、暴雨洪澇災(zāi)害問題和雨水徑流污染問題等,海綿城市這一新興理念應(yīng)運(yùn)而生,其核心是應(yīng)對城市雨水問題,使城市在適應(yīng)環(huán)境變化和應(yīng)對自然災(zāi)害等方面具有良好的“彈性”。本文首先對海綿城市理念的內(nèi)涵、關(guān)鍵問題、主要技術(shù)措施進(jìn)行了探討;將海綿城市理念相關(guān)的低沖擊開發(fā)(LID)、推進(jìn)管、深層隧道系統(tǒng)這三種技術(shù)措施對徑流量削減效果、優(yōu)缺點(diǎn)及適用條件進(jìn)行了文獻(xiàn)歸納,并據(jù)此進(jìn)行綜合比較分析。其次對目標(biāo)地塊屬性和水文情況進(jìn)行概述,在此基礎(chǔ)上,用Infoworks ICM軟件建立了目標(biāo)地塊的現(xiàn)狀雨水系統(tǒng)模型。根據(jù)目標(biāo)地塊現(xiàn)狀雨水管網(wǎng)模型在不同降雨強(qiáng)度和雨型的降雨事件下的模擬結(jié)果,基于海綿城市理念設(shè)計(jì)了LID、推進(jìn)管和深層隧道三套改造方案,建立三種方案的區(qū)域雨水模型。通過對在不同降雨強(qiáng)度及雨型的降雨事件下目標(biāo)地塊三種改造方案的雨水模型進(jìn)行模擬,對照現(xiàn)狀情況,對目標(biāo)地塊徑流總量、徑流峰值的削減情況及徑流時(shí)間參數(shù)的變化情況進(jìn)行總結(jié)分析并對各方案的區(qū)域雨水管網(wǎng)排水性能進(jìn)行評價(jià)。最后,采用模糊層次分析法,初步建立評價(jià)體系,對改造后的三種方案進(jìn)行綜合評價(jià),為海綿城市理念的探討與實(shí)踐提供參考。
[Abstract]:With the intensification of urbanization in China, the regional ecological and hydrological balance has been destroyed. In the process of urban development, the problems of urban water shortage and Rain Water loss, rainstorm and flood disasters, Rain Water runoff pollution and so on, need to be faced. Sponge city emerged as the times require, its core is to deal with the problem of city Rain Water, so that the city in adapting to environmental changes and responding to natural disasters and other aspects of good "elasticity". Firstly, this paper discusses the connotation, key problems and main technical measures of the concept of sponge city. Three technical measures, low impact development (LID), propulsion pipe and deep tunnel system, which are related to the concept of sponge city, are summarized in literature on the effect of runoff reduction, advantages and disadvantages as well as applicable conditions, and a comprehensive comparative analysis is carried out according to these three technical measures. Secondly, the attribute of the target parcel and the hydrological situation are summarized. On the basis of this, the Rain Water system model of the target parcel is established by using Infoworks ICM software. According to the simulation results of Rain Water pipe network model under different rainfall intensity and rainfall type, based on the concept of sponge city, three reconstruction schemes of LID, propulsion pipe and deep tunnel are designed. The regional Rain Water model of three schemes is established. By simulating the Rain Water model of three reconstruction schemes of the target plot under different rainfall intensity and rainfall type, the total runoff of the target plot is compared with the present situation. The reduction of runoff peak value and the variation of runoff time parameters are summarized and analyzed, and the drainage performance of Rain Water pipe network in each scheme is evaluated. Finally, the fuzzy analytic hierarchy process (FAHP) is used to establish the evaluation system and evaluate the three schemes after transformation, which provides a reference for the discussion and practice of the concept of spongy city.
