【摘要】：在消落区开发一种生态透水面板材料作为面层对于护坡系统稳定性至关重要。利用正交实验方法确定了各影响因素对透水面板材料力学性能、透水率等影响,并确定最佳配合比。研究表明,生态护坡系统透水面板材料最佳配合比为:水灰比0.27,硅灰掺量5%,5~10 mm碎石与10~15 mm碎石质量比为3∶1,减水剂掺量1%。各因素对透水面板材料强度的影响顺序为:水灰比硅灰掺量减水剂掺量集料比;对透水率的影响顺序为:硅灰掺量减水剂掺量集料比水灰比。三峡库区风浪侵蚀条件下水平潜流人工湿地护坡系统护坡面层稳定厚度为10.8 cm。
[Abstract]:It is very important for the stability of slope protection system to develop an ecological permeable panel material as a surface layer in the subsidence area. The effects of various factors on the mechanical properties and permeability of permeable panel materials were determined by orthogonal experimental method, and the optimum mix ratio was determined. The results show that the optimum mix ratio of permeable panel material for ecological slope protection system is: water / cement ratio is 0.27, silica fume content is 5 ~ 5 ~ (10) mm and mass ratio of 10 ~ (15) mm macadam is 3: 1, water reducing agent is 1 ~ (-1). The order of influencing factors on the strength of water permeable panel material is as follows: the ratio of water to cement, the ratio of water to dust, and the ratio of water to cement, and the order of influence to water permeability is as follows: the ratio of water to cement of silica fume, water-reducing agent and water-cement is the order of the influence of each factor on the strength of water-permeable panel material The stable thickness of slope protection surface of horizontal subsurface flow constructed wetland slope protection system is 10.8 cm under the condition of wind and wave erosion in the three Gorges Reservoir area.
