Abstract The behaviour and performance of different reinforced slopes during earthquake loading were investigated through a series of shaking table tests. Concrete-canvas and composite reinforcement (geogrid attached to concrete-canvas) were proposed for reinforcing slopes. By considering the effects of different reinforcement methods, the seismic responses of the reinforced slopes were analysed, along with the accelerations, crest settlements, and lateral displacements. The failure patterns of different model slopes were compared using white coral sand marks placed at designated elevations to monitor the internal slide of the reinforced slopes. Both the concrete-canvas and composite reinforcement could increase the safety distance, which ranged from the slide-out point to the back of the model box. The composite reinforcement decreased the volume of the landslide and increased the failure surface angle as a result of the larger global stiffness in the reinforced zone. These results indicate that the recently developed concrete canvas has a better effect on restricting the slope deformation during seismic loading than the nonwoven geotextile reinforcement, and that the use of composite reinforcement could improve the seismic resistance of slopes.

混凝土帆布加固砾石边坡振动台试验

摘要 通过一系列振动台试验研究了不同加筋边坡在地震荷载作用下的行为和性能。混凝土帆布和复合钢筋（附在混凝土帆布上的土工格栅）被提议用于加固斜坡。通过考虑不同加固方法的影响，分析了加固边坡的地震响应，以及加速度、波峰沉降和侧向位移。使用放置在指定高程处的白色珊瑚砂标记来监测加固斜坡的内部滑坡，比较不同模型斜坡的破坏模式。混凝土帆布和复合钢筋都可以增加安全距离，从滑出点到模型盒的背面。由于加固区的整体刚度较大，复合加固减小了滑坡的体积并增加了破坏面角度。这些结果表明，与非织造土工布加固相比，新开发的混凝土帆布在地震荷载作用下抑制边坡变形的效果更好，并且复合加固的使用可以提高边坡的抗震能力。
