多种生态护坡技术在丽水市瓯江堤防工程中的应用研究

Application Research on a Variety of Ecological Slope Protection Technology in Lishui Oujiang River Levee Project

简要介绍了生态护坡的概念及其主要功能,结合丽水市瓯江生态护坡示范段工程,分别对三维植物网、绿化混凝土、连锁水工砌块、三维排水柔性生态袋及椰网植生带5种不同类型的生态护坡技术进行了应用研究,从各技术的施工方法、施工难易程度、工程成本以及工后效果等方面进行了比较分析。研究表明,各方法能达到保持水土、绿化环境、构建"和谐"水陆交错带的目的,因此建议在瓯江类似流域的护岸工程中,可根据施工成本、长期效果等方面进行综合分析,确定合适的生态护坡技术。

This paper briefly introduced the concept and main function of ecological slope protection, combined with Lishui Ou River ecological slope demonstration project. An application research on 5 different types of ecological slope protection technology was eondueted such as three - dimensional plants network, green concrete, chain hydraulie blocks, three - dimensional drainage flexible eco- bags and coconut net vegetative belt. The paper carried out a comtmrative analysis related to construction methods, the degree of construction diificuhy, engineering costs, and workers after effects and on. Studies have shown that these methods ean achieve purposes of soil and water conservation, greening envirolunent and building ＂Harmonious＂ mnphibious Ecotone. Therefore it reconunends that the bank protection works which is sinmilar to Oujiang river can carry, out comprehensive analysis accor（hng to construction cost, long- term effects and so on as to determine the appropriate ecologieal slope protection technology.
