| 摘 要： | 矿井巷道的锚喷支护参数设计时,通常采用工程类比法进行设计,但可能经济上不合理,为了使支护结构尽可能得到优化,从而达到支护费用相对最低的目的,应用组合拱理论对锚喷支护参数进行计算分析,可得出比较合理的参考值。在内蒙古大雁三矿井下巷道设计实践结果表明,组合拱理论是优化软岩巷道锚喷支护参数行之有效的方法之一。

| Abstract: | When carry out the parameter design of anchoring and shotcreting with steel net, an equivalent engineering method could be used, however, this may not be the most economic design. In order to get the best support structure, and achieve the lowest support cost, a built-up arch theory is applied in calculating and analyzing the parameter of anchoring and shotcreting, so as to get a reasonable reference value. The design application in underground tunnel of Dayan No.3 mine Inner Mongolia, shows that the built-up arch theory is an efficient way to optimize the parameter in soft rock tunnel. |
