| 摘 要： | 根据近年来地质力学模型试验的相关资料,结合新疆G217国道某滑坡进行了三维地质力学物理模型的试验研究,用以分析滑坡的变形破坏机制。试验抓住造成滑坡的主要因素,根据所得的岩石力学参数及结构面参数,在几何条件、模型材料、结构面条件等方面都基本满足相似原理的情况下,对模型进行了河流下切、公路开挖等条件的模拟,测量观察边坡的卸荷回弹与层面的弯曲变形情况,利用所测数据分析论证滑坡的形成机制和影响因素。

| Abstract: | According to the information of the geomechanics physical model in recent years, a 3D geomechanics physical model of a slide on G217 highway in Xinjiang is made to research the mechanism of deformation and destruction. The key factors to make the slide is controlled to make the model be similar in geometry, material and fabric with the antetype, then simulate the infection of river ,digging of road and so on, measure the data of the distortion of model, analyze the reason of the distortion and factors of the slide. |
