地震动频谱特性对黄土斜坡地震响应的影响

open access: yesDizhen xuebao
基于西吉、海原和固原的野外调查资料建立了典型斜坡场地概化数值模型,通过选择合理动力人工边界,探究地震动频谱特性对黄土斜坡地震响应的影响。结果表明:① 斜坡加速度受地震动输入频率影响较大,在输入不同频率地震动时,不同监测点加速度峰值放大系数呈现不同变化趋势,同时,速度和位移受地震动输入频率影响较大,各监测点的峰值速度和峰值位移随频率的变化趋势一致;② 低频是诱发斜坡失稳的关键频段,高频振动下斜坡不易发生失稳破坏,斜坡对低频地震波存在放大作用,对高频地震波具有一定的“滤波”作用;③ 随着高程的增加 ...

Mechanism and control of slope instability slip induced by overburden migration in side coal mining [PDF]

open access: yes
Due to multiple factors, open pit mining will form a large amount of trapped coal on the side wall. With the end of internal discharge and reclamation, these trapped resources will be permanently lost, resulting in great waste.
