摘要
对攀钢兰尖铁矿运输平硐局部地段出现失稳现象,运用有限元数值对其进行了模拟,考虑采矿水平不断下降、露天采场爆破震动对其产生的影响,并对采用预应力锚索和钢拱联合支护效果进行了分析,对类似情况的隧洞分析提供一定的借鉴作用。
Abstract
To the instability phenomenon appeared at haulage tunnel local section of a mine,simulation was done by using finite element numerical,effects from continuously decreased mining level,open pit blasting vibration were considered,combining prestressed anchor cable and steel arch support effect were analyzed,provided a certain reference for similar tunnel analysis.
