【摘要】 利用振动台进行了一系列大尺寸边坡模型试验,试验模型尺寸为1.3m×3.58m×0.8m(高×长×宽),坡比1∶1.6。着重观察边坡的破坏性态及其破坏过程,研究了加筋对提高边坡地震稳定性的效果以及加筋长度和加筋密度等对潜在滑裂面和屈服加速度的影响。试验结果再现了地震时边坡的破坏过程,有助于揭示边坡在地震作用下的失稳机制,为边坡的抗震加固提供了参考依据。更多还原

【Abstract】 A series of shaking table tests are conducted to study the failure behavior of a large-scale soil slope.The model slope,1.3m high,3.58m long and 0.8m wide,is built with soil material of a slope ratio 1∶1.6.With the focus on the failure behavior of high slope,improvement on slope stability by appropriate reinforcement with geo-gird and the influence of the reinforcement length and desity on the potential slip face and yield acceleration are studied.The results show the detailed collapsing behavior of side slope under the earthquake excitations will provide useful data to analyze the failure mechanism and seismic response of side slope.更多还原
