| 摘 要： | 根据应力波传播原理分析了水平层状岩体边坡中应力波传播特征,建立了应力波在该类边坡中传播的模型.利用离散元软件UDEC分析了不同频率垂向压缩应力波作用下边坡动力响应规律中的结构面效应.结果表明:边坡中的水平层面对坡顶的动力响应有明显影响.低频应力波作用下,水平层状岩体边坡坡顶的垂向峰值速度较均质坡体相同部位的峰值速度的增...

| Abstract: | Based on the rule of stress wave propagation,the characters of the stress waves propagating in rock slopes with horizontal strata layers are analyzed.A new model about the stress waves propagating in this type of slopes is proposed.The effect of structural plane in dynamic responses of the slopes under periodical compressive load is examined with UDEC.It is revealed that the structural plane plays an important role.Under the action of low frequency compressive waves,the vertical peak ground velocity of slop... |
