植生混凝土护坡技术研究现状及趋势

结合植生混凝土在护坡工程中的优势,从预制栽植结构和现浇喷播结构,总结了植生混凝土的工程结构;从植生基材、植生草种选择、草种筛选、草种组合和植生植物的多样性等方面,研究了植生混凝土的植生结构。根据不同洪水位变动消落区,对岸坡消落区植生混凝土防护布置进行了设计。最后就植生混凝土多孔的微观结构、降碱技术和植生植物长期适应性,提出了进一步研究方向。

Current Situation and Trends of Research on Slope Protection Technology of Vegetation-growing Concrete

: With regard to the advantage of vegetation-growing concrete in the slope protection engineering, in this paper we summarized traits of the engineering structure of vegetation-growing concrete from characteristics of the precast planting structure and the on-site cast spray-seeding structure. We analyzed the structure of vegetation-growing concrete in detail with respect to vegetative substrate, grass seed choice, grass seed screening, grass seed combination and grass varieties, and designed the arrangement of vegetation-growing concrete protection based on different hydro fluctuation zones. Finally we pointed out the direction of further research on the porous microstructure, de-alkalization technique and long-term adaptability of vegetative plants for vegetation-growing concrete.
