| 摘 要： | 为研究滑坡模型试验中不同材料模拟滑带土对模型稳定性的影响,以堆载为试验方法,以位移计为主要的测试手段,进行了采用草木灰、单层塑料薄膜、双层塑料薄膜作为滑面材料的两种工况5组模型试验。通过增加模型上的堆载,增大滑体的下滑力,使滑体最终发生滑动。根据试验的初始稳定状态、最终稳定状态及监测到的模型位移曲线,确定滑坡的极限平衡状态;同时根据最终加载量,反算出滑带土模拟材料的相似抗剪强度;得出不同滑面材料的稳定性及相似抗剪强度,为滑坡支挡模型试验提供试验基础。

| Abstract: | In order to study the influence on the stability of model by slip soil simulated with different materials in the landslide model test,taking loading as experimental method and using displacement meter as a mainly test means,five model tests between two working conditions with plant ash,plastic film and double-plastic film as slip material are conducted.Finally,landslide is slipped by increasing load of the model and the downslide strength.Limit equilibrium of landslide can be determined according to the ini... |
