中文摘要：
为了研究不同粒径的块体在散体边坡上的滚落规律,设计了室内相似实验,选择不同粒度的散体物料堆载成平直、凹形、凸形3种形状的边坡,并选取10个不同尺寸的块体,模拟大块从散体边坡上的滚落规律,并根据大块运动情况建立了力学和运动方程,对实验数据和现场统计数据进行对比分析,结果表明：大块滚落过程中,影响其滚动轨迹的主要因素有大块岩体的几何结构和重量,结构均匀的大块以滚动为主,运动轨迹近似为直线;畸形的大块以滑动为主,轨迹为不规则曲线;块体的重量越大,滚落距离越长,瞬时折减的能量越大。大块在不同几何结构的散体边坡上滚落的距离排序为：凹形边坡〉平直边坡〉凸形边坡。
英文摘要：
In order to study the rule of different sized rock rolled on the granular slope,an indoor similarity experiment was designed by choosing different granular materials to be stacked into flat,concave and convex slopes and taking 10 different sized rock blocks to simulate the rule of large rock rolling on the granular slope.Mechanics and motion equation were established according to the large rock movement on granular slope.After comparing the experimental data with field statistical data,the results show that the main factors affecting the rolling track of large size rock during rolling process are geometric structure and weight,the uniform structure of rock is mainly in rolling and motion trajectory approximate to linear,while the deformity rock is predominately in sliding and motion trajectory in irregular curve.The moving distance and instantaneous reduction energy are increased with the weight of large rock.The order of large rock rolling distance on different geometric structure slope is concave slope 〉flat slope 〉convex slope.
