摘要
在分析岩石动力特性的基础上,对抚顺矿区由矿震导致的西露天矿边坡动力响应进行了分析。结果表明,由于变形过程的不可逆性,动力条件下,边坡的塑性区增加,形成塑性破坏区的累积破坏。与塑性区相对应,随着震动次数的累加,边坡的位移也会累积增长。
On the basis of the analysis of rock＇s dynamic feature,an analysis is made of the slope dynamic response caused by mine earthquake in Fushun Western Open Mining Area. The result shows that due to the irreversible distortion process, the plastic area of the slope increases under the influence of dynamic ,and thus there arises the accumulative destruction to the plastic area. With the increase of earthquake,the displacement of the slope accumulatively incerases.
