为分析矩形巷道围岩应力与变形的分布规律，利用FLAC3D数值模拟软件对矩形巷道围岩的稳定性进行了模拟分析，并给出了矩形巷道支护建议。研究结果表明，矩形巷道顶、底板主要为拉伸破坏，两帮主要为剪切破坏，且顶、底板破坏深度大于两帮，运用锚杆支护能较好地解决矩形巷道的支护问题。
為分析矩形巷道圍巖應力與變形的分佈規律，利用FLAC3D數值模擬軟件對矩形巷道圍巖的穩定性進行瞭模擬分析，併給齣瞭矩形巷道支護建議。研究結果錶明，矩形巷道頂、底闆主要為拉伸破壞，兩幫主要為剪切破壞，且頂、底闆破壞深度大于兩幫，運用錨桿支護能較好地解決矩形巷道的支護問題。

In order to analyze the stress and deformation of rectangular roadway surrounding rock, the stability of rectangular roadway surrounding rock are analyzed by the numerical simulation software FLAC3D, and the support advice are put forward basing on which. The results show that the roof and lfoor of rectangular roadway mainly for the tensile failure and the two sides shear failure, and the former’s damage depth is larger than the latter. Bolting can solve the supporting problem of rectangular roadway well.
