结果表明：与直接粘贴CFRP布相比，采用剔槽植入钢筋置换混凝土灌胶再粘贴CFRP布复合加固方案加固的梁极限承载力有显著提高，开裂荷载及延性有较大提高；
Results show that ultimate bearing capacity of RC beam strengthened by composite CFRP sheets is much higher than that of direct pasting CFRP. Cracking load and ductility are improved higher too.
对于植入的钢筋，如同预埋一样，钢筋强度能被充分利用。
The implanted steel bars is same as the build-in steel bars, the strength of them are sufficiently utilized.
而在界面上植入抗剪钢筋后，能大幅度提高了新老混凝土的粘结抗剪强度。
