Wrapping carbon fiber reinforce polymer sheet (CFRP) and bonding Angle steel are two common methods in reinforced concrete columns reinforcement engineering nowadays.
当前的加固工程中，粘贴碳纤维片材和粘钢是较常用的两种方法。

In the second step, the prestressed cable is used as reinforced support to the roof plate, and the reinforcement by bolting and grouting with inside grouting bolt is applied to base Angle.
然后再采用预应力锚索对顶板进行加强支护，且对巷道底角采用内注浆锚杆进行锚注加固。

When it was tensile failure, the curve of stress-strain relationship was softening and the reinforcement only increased the angle of internal friction of soil.
