【摘要】 顺层滑坡是破坏最多、危害最大的边坡.长大顺层边坡失稳往往并非一次下滑,而是多次分段下滑,这与边坡体滑面上的锁固效应有关.根据滑移坡体的运动特征,提出坡体粘滑运动的数学模型,导出整体运动及部分协调运动情形下的位移、速度、加速度等运动量的计算公式,从而建立起坡体运动与其几何尺寸、物理参数、受力状态的关系,进一步讨论划分边坡的不同破坏形式.更多还原

【Abstract】 The bedding sliding slop is the most destructible and hazardous one.Destabilization of long and big bedding slope does not always occur once and for all as it slides down but takes place in the manner of multiple multistage slide-off,which is related to the locking effect of the sliding surface.A mathematical model of stick-slip movement of sliding mass was proposed based on it movement feature and the computation formula of displacement,velocity,and acceleration of whole slope movement and its partial coordinate movement was derived,so that the relation of the slope movement to its geometrie dimension,physical parameters,and stress state was established.The different mode of slope destruction was also discussed and divided.更多还原
