淹水区边坡的生态型护坡技法及其耐久性研究

Streamlined ecotypic slope protection techno-method and durability of the flooded field

通过植生袋状垫(一种新型生态植生材料)、生态混凝土(多孔、透水性混凝土)、卵石(自然石)等近自然界材料的不同组合,创作出的最新生态型护坡技法来对淹水区坡面进行设计、护坡,不仅可以充分保证护坡工程安全性、经济性,而且能起到对生态环境维持和改善的功能。针对国家863“十五”重大科技专项“镇江城市水环境质量改善与生态修复技术研究与示范”总课题第三分项中的生态堤淹水区坡面,采用三种不同的生态护坡技法进行了现场实施,同时对生态护坡技法中的生态混凝土的耐久性等进行了调查、研究和评价。结果表明:所提出的生态护坡技法能够谋求和保证与生态系统的调和或共生、创造舒适的环境,并且所用生态混凝土具有良好的耐久性。

The streamlined ecotypic slope protection techno-method to design and protect the slope of the flooded field can be produced, by various combination of vegetation baggy cushion（a new ecological vegetation material）, ecological concrete （porous and dank concrete）, scree（natural stone）, etc., adjacent natural materials. This techno-method can not only guarantee the security and economy of slope protection project fully, but aslo maintain and improve the environment. We adopt three different ecotypic slope protection techno-methods to do field-test, according to the ecotypic bank aspect of the third subentry of state 863 “fifteen” grand science and technology special proiect which is entitled as “research and demonstration of ZhenJiang city＇s water environment improvement and ecotypical renovation technology” ; meanwhile, we make a survey, investigating and evaluating the durability of ecotypic concrete. The result shows that： our ecotypic slope protection techno-method owns effect in seeking for and assuring natural consonance, intergrowth and creating comfortable environment, furthermore ecotypic concrete has fine durability.
