摘要:
 以透水石模拟岩质边坡，通过植被混凝土与透水石界面的直剪试验，研究植被混凝土与岩质边坡界面间的抗剪强度与水泥和绿化添加剂掺量之间的关系，并通过pH测试研究植被混凝土在满足界面抗剪强度条件与植物生长条件两者间的相适应性。结果表明，随着水泥掺量的增加，植被混凝土—石界面之间的抗剪强度逐渐增大，植被混凝土的pH值也随之逐渐升高；随着绿化添加剂掺量的增加，植被混凝土—石界面之间的黏聚力和内摩擦角呈现不同的发展趋势，植被混凝土的pH值逐渐降低。当水泥掺量为6%，绿化添加剂掺量为50%至75%时，相较于普通黏土-石界面，植被混凝土-石界面间的黏聚力降低80.5%至60.2%，内摩擦角降低24.3%至53.6%，同时又能满足植物生长的条件。
Abstract:
 Rock slope is simulated by pervious stone. Vegetation concrete and direct shear test of permeable rock interface are used to study the interface between concrete and rock slope vegetation of shear strength and the relationship between the cement additive dosage and greening. The pH test is used to study the adaptability between vegetation concrete in the interface shear strength and growth condition of plant. The results show that with the increase of cement content, the shear strength between the interfaces increases gradually, and the pH value also increases gradually. With the increase of the amount of green additives, the cohesion and internal friction Angle between the interfaces present different development trends, and the pH value gradually decrease. When the cement content is 6% and the greening additive content is 50% to 75%, compared with the common clay-stone interface, the cohesion between the vegetation concrete-stone interface is increased by 80.5% to 60.2%, and the internal friction Angle is increased by 24.3% to 53.6%, which can meet the conditions of plant growth.
