Experimental Study of Stick-Slip Behaviour of Dry Granular Materials

  • 摘要: 为了研究浅源地震的诱发机制,基于室内三轴试验,对颗粒材料的粘滑震动特性进行了分析. 采用颗粒直径为0.6~0.8 mm的玻璃珠,在围压为30、60、100、200、400 kPa和600 kPa的条件下,以0.02 mm/min的轴向应变速率,开展干燥、密实玻璃珠的固结不排水三轴压缩试验,结果表明:试样偏应力主震和偏应力应变间距随着围压的增大而增大;除了初始压密阶段外,体变-应变曲线中所有体积的突然收缩均与粘滑震动有关;在30、60、100 kPa围压条件下,围压-应变曲线中出现较多尖而窄的波峰和波谷;在200、400 kPa和600 kPa围压条件下,围压-应变曲线中只有尖而窄的波谷;玻璃珠类颗粒材料发生粘滑震动过程中既有静摩擦也有转动摩擦;颗粒之间应力链的连续变形和破坏是引起颗粒粘滑震动的根本原因.
