摘要
本文采用有限单元法计算了某地下矿山四种不同断面形状的巷道围岩的二次应力分布状态。在判断最优巷道断面时,采用了Fuzzy数学的贴近度理论,这种新理论为矿山定性与定量相结合选取最佳巷道断面提供了一种有效的方法。
This paper computes the secondary stress distriution of many sections of the main roads in a underground mine with finite element method. When analyzing the optimal section form,this paper applies the theory of Fuzzy Maths and chooses the optimal section form of main road in the min from manysections. This method with qualitative and quantitutive is very important in selecting the optimal section of a specific mine.
