淹水区生态型护坡设计及抗冻融性能分析

针对淹水区坡面进行护坡的必要性和传统护坡技法的缺陷，提出了应用生态型护坡技法——中日植生材料（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）等近自然界材料的组合，进行设计、护坡．国家863专项“镇江水环境处理”中的生态堤采用生态型护坡技法进行设计，通过对该技法中组成材料的分析和生态混凝土耐久性的主要影响因素——冻融进行调查、研究，认为所提出的生态护坡技法不仅能充分保证护坡工程安全性、经济性，还可维持和改善生态环境，谋求与生态系统的调和或共生，创造舒适的环境，而且所用生态混凝土具有良好的抗冻融性．

Design and analysis of freezing-thawing resistance about ecological slope protection in flooded field

Aiming at the flooded field slope protection,and to improve the traditional techno-method of slope protection,a new techno-method of ecological slope protection is proposed,which combines a new ecological vegetation material,ecological concrete(porous,dank concrete),scree(natural stone) and adjacent natural materials,in the design and protection of the slope of the flooded field.This techno-method can not only guarantee the security and economy of slope protection project,but aslo maintain and improve the environment.The method has been applied to the design of the ecotypic bank aspect in the National 863 Project for water-management of Zhenjiang.By analyzing the materials,investigating and evaluating the freezing-thawing cycle durability of ecotypic concrete it is found that this techno-method has effects of seeking for natural consonance or intergrowth,creating comfortable environment,securing the project of slope and improving the ecological environment.techno-method of ecological slope protection;China-Japan vegetation material;ecological concrete;freezing-thawing resistance
