摘　　要：拱形巷道在复杂应力条件下的变形以及破坏形式呈多样化,与围岩性质、地应力和支护结构相关。利用大型有限元软件ADINA对邯郸某煤矿拱形巷道进行数值模拟,可以观察到巷道随着开挖的进行,变形破坏的全过程,其模拟结果与实际情况相符,为在复杂条件下拱形巷道的变形研究及稳定分析提供较好的方法。The distortion and destroy form of coved laneway in complicated stress condition are diversity, and it is relative with rock character, crustal stress and shoring structure. Utilizing large-scale finite element software which is called ADINA to do numerical simulation of one coUiery in Handan, the whole destroy process of the laneway is clearly saw which accompanied with the excavating, and the result is the same with the practical situation, providing a better method for the coved laneway deform research and stabilization analyse in complicated condition.
