【摘要】：随着经济快速发展,城市化进程不断加快,城市面貌日新月异,然而城市化进程中一直被忽略的城市排涝问题却越来越成为影响城市安全的一个重要隐患。尤其是近5-10年,我国大部分特大、大型城市均遭受过“水漫金山”,外表光鲜的现代化城市在暴雨来临瞬间原形毕露,“城市看海”成为了一个网络热词,扰乱了城市的正常秩序,危及市民的人身财产安全。如何应对城市内涝,提升排涝防涝能力,保障城市安全成为一个亟须解决的课题。本文以城市排涝为研究对象,在2014年国务院出台的《城镇排水与污水处理条例》对城市排水提出更高要求的大背景下,从城市排涝的政策、管理和技术三个层面入手,通过对三大层面的成因分析：如排水设计标准不高,存在“以排为主”的理念偏差,如城市发展土地开发利用程度与系统性排水规划和建设不配套,如排水设施管理养护缺失,如新技术应用不足等。通过借鉴国内外成熟经验和技术,结合现状,运用数理统计和模型计算等研究方法,提出如何从城市排涝的政策、管理、技术三方面入手,如何建立“蓄、滞、渗、排”四位一体的排涝理念,进一步落实住建部提出的“海绵城市”概念,提升城市排涝技术和手段,建立城市防涝体系来缓解城市内涝,提高城市防涝排涝能力。最后以杭州城市排涝为实例,通过历史资料的统计进行内涝风险评估LID(Low Impact Development)技术数学模型的量化分析以及新技术新工艺的应用,对前文提出的政策、管理、技术三方面进行论证,并通过了实践的考验,初步提升了城市排涝防涝能力,也验证了研究成果的有效性和可行性。
[Abstract]:With the rapid development of economy, the process of urbanization is accelerating, and the appearance of the city is changing with each passing day. However, the problem of urban waterlogging, which has been neglected in the process of urbanization, has increasingly become an important hidden danger affecting the safety of cities, especially in recent 5-10 years, most of our country is extraordinarily large. Large cities have suffered from "overflowing Jinshan", the appearance of the modern city in the appearance of the arrival of rainstorms, "City to look at the sea" has become a hot word of the network, disrupting the normal order of the city. How to deal with urban waterlogging, how to improve the ability of waterlogging and waterlogging prevention, and how to protect urban safety has become an urgent problem to be solved. This paper takes urban waterlogging as the research object. In 2014, the regulations on Urban drainage and sewage treatment issued by the State Council put forward higher requirements for urban drainage, starting with the policy, management and technology of urban drainage. Through the analysis of three levels of causes: such as drainage design standards are not high, there is a "drainage mainly" concept deviation, such as urban development and land use degree and systematic drainage planning and construction do not match. Such as the lack of maintenance of drainage facilities management, such as inadequate application of new technologies. Through the use of domestic and foreign mature experience and technology, combined with the current situation, the use of mathematical statistics and model calculation and other research methods. This paper puts forward how to start with the policy, management and technology of urban waterlogging, how to establish the concept of "storage, stagnation, seepage and drainage", and how to further implement the concept of "sponge city" put forward by the Ministry of Housing and Construction. To improve the technology and means of urban waterlogging drainage, to establish urban waterlogging prevention system to alleviate urban waterlogging, improve the ability of urban waterlogging prevention and drainage. Finally, take Hangzhou city waterlogging as an example. Based on the statistics of historical data, the quantitative analysis of the mathematical model of LID(Low Impact development and the application of new technology and new technology are carried out. This paper demonstrates the policy, management and technology mentioned above, and has passed the test of practice, which has preliminarily improved the ability of urban waterlogging and waterlogging prevention, and also verified the validity and feasibility of the research results.
