首先对U型桥台的主要开裂形式及导致开裂的原因做了统计,针对一些开裂的处理方法做重要阐述;介绍了壁可法的工作原理,说明了壁可法在处理横向裂缝中的作用和优势,通过试验和实际工程比较表明:壁可法对修复桥台横向裂缝具有很大作用,通过壁可法加固桥台可使修补后混凝土抗压强度回到无裂缝时实测强度值的94%左右,在同一位置破坏面积小于总面积的15%。由此说明壁可法对桥台横向裂缝的补强具有很大的作用,在实际工程运用中具有很大的意义。
First of all, the main cracking forms of U-shaped abutments and the causes of cracking are analyzed, and some methods of cracking are elaborated. The principle of workable walls is introduced, and the role of wallable methods in the treatment of transverse cracks The advantages and disadvantages of the proposed method are as follows: The comparison between the test and the actual engineering shows that the wall method has a great effect on the repair of transverse cracks in abutments, and the abutment can be used to reinforce the abutment so that the compressive strength of repaired concrete can return to the measured value %, Damage area in the same place is less than 15% of the total area. It shows that the wall can have a great effect on the reinforcement of transverse cracks in the abutment, which is of great significance in practical engineering application.
