受力条件恶化严重抑制着软岩巷道支架支撑能力的发挥。

Poor loading condition will severely limit the supporting capacity of the supports in soft strata.

在巷道金属支架的设计与计算中，不但要对结构进行强度和刚度计算，而且还要进行稳定性的验算。

In designing and calculating the tunnel metallic support, not only the structure's strength and stiffness should be calculated, but also the stability should be checked.

结果表明，利用有限元法分析巷道金属支架的稳定性是可行的。

The results show that it is feasible to use FEM to analyze the stability of the metallic support.
