基于土工聚合物的绿色边坡防护系统
|
摘要
采用基于土工聚合物的新材料构建绿色边坡防护系统是解决发展与环保之间矛盾的有效途径之一。通过整合柔性面层边坡防护体系、带横隔板的多层结构生态边坡防护体系和钢塑复合外锚固体系等一系列创新成果构建了分别适用于挖方和填方边坡的新型绿色防护系统。提出的新型绿色防护系统的设计思路和方法,可为解决高陡边坡厚层基质客土的生态防护问题提供参考。
It is an effective way to solve the contradiction between development and environmental protection to build green slope protection systems by using new materials based on geopolymer. Through integrating a series of innovative achievements,such as the flexible facing slope protection system,the multi-layered ecological slope protection system with transverse baffles,and the steel-plastic composite external anchoring system,a new green protection system suitable for excavating and filling slopes was constructed. In addition,the design idea and method of the new green protection system could provide a reference for resolving the problem of ecological protection with thick guest-soil on high-steep slopes.
