摘 要：不同類型的滑坡具有不同的變形破壞行為，同一斜坡在不同受力條件下也可能表現(xiàn)出不同的變形破壞行為。為了能在室內(nèi)實(shí)際觀測(cè)到斜坡在不同受力狀態(tài)下的變形破壞行為，設(shè)計(jì)制作了可以調(diào)整角度的模型試驗(yàn)框架，自主研發(fā)了模型位移測(cè)量裝置，通過(guò)大量測(cè)試最終選擇成都粘土作為滑帶土材料，開展了近一年的滑坡變形破壞行為的物理模擬試驗(yàn)研究，共完成7種傾角14組模擬試驗(yàn)，得到了不同受力條件下的滑坡變形-時(shí)間線簇，進(jìn)一步揭示了滑坡變形-時(shí)間曲線的特征，為斜坡變形-時(shí)間曲線類型歸納提供了依據(jù)。

Abstract： Different types of landslide deformation and failure behavior is different， the same slope may also exhibit different deformation and failure behavior under different stress conditions. In order to observe slope deformation and failure behavior in different stress condition， a model test framework is designed which angle can be adjusted， and we independent research and development of the model displacement measuring device. We choose Chengdu clay as the slide zone soil materials through a lot of tests， the development of the study on the physical simulation test of the slope deformation and failure of nearly a year， completed 7 kinds angle and 14 groups simulation test. Acquired deformation time curves under different stress conditions by physical simulation. The datas further reveals the characteristics of the landslide deformation-time curve， provides the basis for induction of the curve types of slope deformation-time.

Key Words： Landslide； Sliding zone； Physical simulation； Deformation-time curve
