摘　　要：Through the description of the deformational features of the surrounding rockaround high stress engineering soft rock roadways,the coupling stabilization principle ofinner and outer structures in surrounding rock was put forward.The supporting principlesof high stress engineering soft rock roadway (high resistance and yielding support,timelysupport,high strength and high stiffness supports) were proposed,which were applied inengineering practices,and obtained better achievements.Through the description of the deformational features of the surrounding rock around high stress engineering soft rock roadways, the coupling stabilization principle of inner and outer structures in surrounding rock was put forward.
