摘　　要：通过对软岩巷道Ｕ形钢支架后部进行充填的试验效果、作用机理的分析，证明架后充填可以显著地提高Ｕ形钢支架对软岩巷道围岩变形的控制能力。Through experiment and analysis,it is proved that by carrying out filling behind the support,the control of soft country rock and tunnel deformation by means of U-shaped steel supporter can be improved significantly thus it is favorable to stabilize tunnel.
