A series of shaking table tests were conducted on reinforced slopes to study the slope dynamic characteristics. The influence of concrete-canvas tilt degrees on the seismic response was studied. By considering the effects of different concrete-canvas tilt degrees, the seismic responses of the reinforced slopes were analyzed, along with the accelerations, crest settlements, and horizontal 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. Several round markers were placed on the slope surface to compare the deformation before and after shaking with different amplitudes. The results indicated that with the increase in concrete-canvas tilt degrees, a better reinforcing effect was obtained, and 30° reinforcement reached a threshold level, the slide-out point shifts from the crest of the slope to the middle of the reinforced model. The bottom 2/7th zone of the slope was relatively stable during the earthquake and the reinforcement was ineffective at the bottom of the slope. When both considered the influence of reinforcing effect and construction difficulty, 20° is the suitable tilt degree in concrete-canvas reinforced slopes. The characteristics of increasing strength of the concrete canvas make it suitable for the application in slope protection.

混凝土帆布加固斜坡的地震响应:倾斜度对加固的影响

在加筋边坡上进行了一系列振动台试验,以研究边坡动力特性。研究了混凝土-帆布倾斜度对地震响应的影响。通过考虑不同混凝土-帆布倾斜度的影响,分析了加筋边坡的地震响应,以及加速度、坡顶沉降和水平位移。使用放置在指定高度的白色珊瑚砂标记来比较不同模型边坡的破坏模式,以监测加固边坡的内部滑动。在坡面上放置了几个圆形标记,以比较不同幅度摇动前后的变形情况。结果表明,随着混凝土-帆布倾斜度的增加,获得了更好的加固效果,30°钢筋达到阈值水平时,滑出点从斜坡的顶部移动到钢筋模型的中间。地震时坡底2/7区相对稳定,坡底加固效果不佳。当同时考虑加固效果和施工难度的影响时,20°是混凝土帆布加筋边坡的合适倾斜度。混凝土帆布增加强度的特点使其适用于边坡防护中的应用。
