摘要
根据大贾庄铁矿跨河大桥4号墩4-1#桩基偏位处理工程实例,针对桥梁桩基施工中产生的桩基偏位问题,通过计算桩基偏位受力情况,采用在4-2#和4-3#桩基增加连梁的处理方法,改善了偏位桩基偏心受力不利的影响,达到了在较短的工期内,安全、经济地处理好偏位桩基的目的。
According to the engineering examples of the treatment to Dajiazhuang iron ore river crossing bridge No.4 pier of 4-1# pile foundation deviation, in view of the problem of pile foundation deviation in construction of bridge, through the calculation of pile foundation deviation stress, the paper adopts a meth- od of increasing coupling beam with 4-2# and 4-3# foundation, which improves the adverse effect of ec- centric force of deviation pile, achieves the purpose of safety and economic treatment of the pile deviation in a short time.
