摘要
应用变截面桩计算理论详细分析断桩发生后钻桩法处理断桩的受力特点,进行了断桩处理设计,最终实施钻桩法处理了断桩,确保了大桥的按时通车。3年多运营情况表明钻桩法处理断桩获得了成功,归纳总结了钻桩法处理断桩的理论依据、简化计算方法、适宜场合等。
The features of the mechanical properties of broken piles handled by drilling pile method are analyzed in details by means of the calculation theory of variable cross section piles. The design for handling the broken piles is made and the handling of the broken piles is implemented by the drilling pile method, which ensures that the bridge with the broken piles handled is open to traffic on schedule. More than three years' operation of the bridge indicates that the way to handle the broken piles by the method is successful. In this paper, the theoretic basis for the drilling pile method, the simplified calculation and applicable conditions of the method are also summarized.
