| 摘 要： | 通过多组模型的室内模拟试验,模拟了锚固边坡在不同荷载条件下沿圆弧和折线2种模式的破坏过程,分析了不同岩土体边坡锚固失效时稳定性的不同特性,以及群锚作用条件下单锚失效时边坡的力学及变形特点,进而研究了边坡锚索失效对边坡稳定性的影响机理。研究结果表明:在荷载作用下,边坡上排锚索比下排锚索先破坏,失效锚索的锚固力会向其他锚索转移;圆弧破坏边坡不同位置的锚索失效对边坡稳定的影响与锚索所在位置关系不大,而折线破坏的边坡不同位置锚索破坏对边坡稳定性的影响不同。

| Abstract: | The failure processes of anchorage slope in two failure modes(the arc mode and broken line) under different loads were simulated through serials of laboratory experiments.Based on the experiment simulations,the characteristics of slope stability were analyzed under the condition of various types of rock and soil slopes when anchors are out of action.The characteristics of slope reinforced by group anchor were studied in terms of mechanics and deformation.The effect of failure of anchor cables on slope stabi... |
