Research on Application of Cast-in-place Eco-concrete to Disaster Control and Ecological Restoration
摘要
通过研究生态混凝土的微观结构与孔隙率、透水性、强度三者的耦合关系
对生态混凝土的孔隙结构特征进行了分析
提出孔隙结构分布值R是影响生态混凝土的重要指标。通过对生态混凝土护坡的防冲刷机理分析和试验验证
提出了边坡生态恢复和灾害治理相结合的方法
即采用生态混凝土和预应力锚索框架格护坡。对河南洛阳段高速公路一侧的土质高陡边坡
在进行稳定性分析的基础上应用该方法
并且对后续的生态恢复效果进行了研究。研究结果表明:该方法适宜于坡度较大的边坡
结合预应力锚索框架格能对滑坡起到防治作用;降雨条件下抗冲刷能力强
植物覆盖率较高
对周围的生态恢复起到了一定的作用。
Abstract
From the relatioship between microscopic structure and porosity
permeability and strength
the pore structure feature of ecological concrete was analyzed.The paper puts forward that the pore structure distribution value Ris an important index of ecological concrete.Based on the ecological concrete bank protection anti-scouring mechanism analysis and experimental verification
this paper proposes combining slope ecological restoration and disaster control method
namely ecological concrete and prestressed anchor cable frame revetment.It was applied to a soil high steep slope on one side of Henan Luoyang expressway on the basis of stability analysis
and the subsequent effect of ecological restoration was observed.Research results show that:the method is suitable for the steep slope.Combining with prestressed anchor cable fram it can play a role in prevention of landslide.It has high rainfall erosion resistant capability
high plants coverage rate and plays a certain role in ecological restoration.
