【摘要】：随着社会的不断进步,经济的快速发展,人们对生活环境质量要求越来越高。城市河道作为城市生态环境的重要组成部分,对城市生态环境的建设和优化起着重要的作用。在城市化建设初期,侵占河道水域及岸线、生活工业废水和垃圾随意排放等不良的城市河道利用模式导致城市内河河道功能减退,水质下降、水域生态恶化。为适应现代化的城市建设,国家层面已提出在全社会大力倡导生态文明建设,而生态护岸技术研究更成为城市河道堤岸工程的重要实践课题之一。本文以那考河河道整治工程中的生态护岸形式作为研究对象,采用理论与实际工程设计及施工调查相结合的研究方式,通过对本项目河段功能规划及生态护岸形式的设计理论研究,比选出适合不同河道断面需要的护岸基础及生态护岸形式。并对所设计的生态护岸形式的施工效果进行分析与评价,总结得出:三维植被网生态护岸不适于南宁地区使用;生态互锁砖生态护岸不适合于岸线曲折及常水位面以下的河道护岸使用。提出适合于南宁地区气象、水文特点及城市河道特点的生态护岸结构形式,并摸索出一套有效的质量控制措施。本文对那考河护岸工程中的生态护岸形式进行研究,旨在为南宁市进一步合理利用生态护岸形式奠定基础,为南宁的水城建设和海绵城市建设提供宝贵的经验。
[Abstract]:With the continuous progress of society and the rapid development of economy, people have higher and higher demands on the quality of living environment. As an important part of urban ecological environment, urban river course is an important part of urban ecological environment. It plays an important role in the construction and optimization of urban ecological environment. In order to adapt to the modern urban construction, the bad urban channel utilization mode, such as domestic industrial waste water and garbage random discharge, has led to the decline of urban inland river channel function, the decline of water quality and the deterioration of water ecological conditions. At the national level, it has been proposed that the construction of ecological civilization should be vigorously advocated in the whole society. The study of ecological revetment technology has become one of the most important practical subjects in urban river channel embankment engineering. By combining theory with practical engineering design and construction investigation, this paper studies the design theory of river reach function planning and ecological bank protection form of this project. Comparing with selecting the revetment foundation and ecological bank revetment form suitable for different river sections, and analyzing and evaluating the construction effect of the designed ecological bank revetment form, it is concluded that the three-dimensional vegetation net ecological bank revetment is not suitable for use in Nanning area; Ecological interlocking brick ecological revetment is not suitable for river revetment with twists and turns along the shore line and below the surface of constant water level. The ecological bank revetment structure suitable for meteorological, hydrological and urban river characteristics in Nanning area is put forward. A set of effective quality control measures has been found out. This paper studies the ecological bank revetment form in Naokao River revetment project in order to lay a foundation for the further rational use of ecological bank revetment form in Nanning City. It provides valuable experience for the construction of water city and sponge city in Nanning.
