摘要
对一强度不足的桩柱式桥墩,采用增大截面法进行加固。加固的思路为:在满足既有墩柱竖向承载力的前提下,可采用增大截面法,在墩柱周围布置钢筋进行抗弯加固。计算结果及加固后效果均表明,该方法对强度不足的桩柱式桥墩加固是可行有效的。
The increased cross section method for reinforcement is adopted for pile column bridge pier with insufficient strength. The reinforcement idea is that adopt increased cross section method to perform bending resistance reinforcement around the pier column by arranging reinforcing steel bar in the premise of meeting the requirement of vertical reinforcement show that strength. bearing capacity of existing pier column. The calculation result and the effect after the this method is feasible and effective for reinforcement of pile column bridge with insufficient
