In-situ monitoring gave the following results: 1 a tension stress zone occurred at the bottom of reinforced rock mass which indicated that the role of rock bolting was remarkable; 2 stress concentration at surrounding rock of main shaft was gradually transferred from shaft wall to complete rock mass far from shaft center; 3 vertical displacement was gradually smaller from up to bottom and from center to outside of the reinforced loose rock mass.
首先,建立了主溜井三维有限元计算模型,模拟了主溜井围岩的塌落破坏过程和加固后的加固体的稳定性及变形特性;同时,还采用多点位移计等对加固体的稳定性进行了实地监测。计算结果表明:网棚锚注加固体的纵剖面上的压力和位移规律是①加固体下部局部出现拉应力区,表明锚杆的使用是合理的;②加固体内的应力由塌落中心向周围围岩过渡,应力越来越大,最终将荷载传至围岩中;③从下到上下沉逐渐减小;④从加固体中心到周围下沉位移逐渐减小,且近似一条抛物线。
