边坡滚石是一种常见的工程地质灾害,滚石运动的复杂性往往与其影响因素密切相关。针对滚石从发源地到终止点之间的运动形态,对影响滚石运动轨迹和能量转换的诸多参数进行了探讨,通过理论比对分析,筛选出主要的影响参数,即边坡坡面还原系数、坡面摩擦角、坡面粗糙度、滚石自转的角速度和滚落状态5方面进行了系统的模型试验和数值模拟分析,总结出了外在因素以及内部因素耦合作用下的滚石的运动形态。为进一步深入研究滚石运动奠定了基础,为制定相应的工程防护措施提供了参考依据。
Rolling stones is a common engineering geological disasters, the complexity of the rolling stones are often closely related with its influencing factors. Aiming at the movement patterns of the stones from the place of origin to the termination point, many parameters that affect the trajectory and energy conversion of the stones are discussed. Through theoretical comparison and analysis, the main influence parameters are selected, namely the slope reduction coefficient, Slope friction angle, slope roughness, roll rotation angular velocity and rolling state of 5 aspects of the system model tests and numerical simulation analysis, summed up the external factors and the internal factors under the action of rolling stones movement. It laid the foundation for further study of the rolling stone movement and provided reference for formulating the corresponding engineering protection measures.
