摘　　要：为研究生态混凝土护坡技术对红黏土边坡的改良作用,对生态混凝土的力学性能与植生性能进行试验,结果表明30%孔隙率的生态混凝土的28 d抗压强度能达到14.4 MPa, 28 d抗折强度能达到2.8 MPa。生态混凝土内部环境为微碱性,在生态混凝土上覆土种植耐碱性植物后14 d植株高度能达到16.5 cm,且植物覆盖率能达到80%,植物生长状况良好,植物茎叶通过降雨截流、削弱溅蚀和抑制地表径流,有效减弱了雨水冲刷作用。生态混凝土与植物护坡相结合增加了边坡的稳定性,改善生态景观和驾驶环境。In order to study the improvement effect of ecological concrete technology on red clay slope,the mechanical properties and planting properties of ecological concrete are tested.The results show that the compressive strength of ecological concrete with 30%porosity can reach 14.4 MPa,and the folding strength of 28 d can reach 2.8 MPa.The internal environment of ecological concrete is slightly alkaline.After planting alkaline resistant plants,the plant height can reach 16.5 cm,and the plant coverage rate can reach 80%,and the plant growth is in good condition.The stems and leaves of plants are blocked by rainfall,weaken and inhibit the surface runoff,which effectively weakens the effect of rainwater erosion.The combination of ecological concrete and plant slope protection increases the stability of the slope and improves the ecological landscape performance and driving environment.
