中文摘要：
针对岩体边坡块体滑落过程，利用自行研制的变角度空间块体滑落模型平台，开展块体滑落系列实验，并与基于离散元法开发的3DEC程序对岩质边坡进行三维模拟分析，建立关键块体的非连续变形动态分析模型，模拟了块体滑落过程，得到动态位移图，最终得到楔形块体双面滑落与单面滑落的分界角度在40°～50°这个区间，对边坡工程的开挖支护有一定借鉴意义。
英文摘要：
Here, the sliding process of rock blocks is mainly studied with the self-made angle-variable spatial rock-mass sliding model. The experiments of rock block sliding are implemented, and also combined with the 3DEC program based on the discrete element method, the 3-D simulation analysis for the rock slope is made. In this way, the dynamic analysis model of discontinuous deformation is set up, the sliding process of rock blocks is simulated, and the displacement graph is obtained with the analysis of 3DEC. At last, the demarcation angle between the double sliding and single sliding of the wedge-shaped rock blocks is in the region of 40°to 50°. All these as mentioned above are useful for the excavation and support in slope engineerings.
