摘要

缺陷桩基处理是工程建设中常见的困难问题。以但渡大桥工程出现的桩基混凝土强度等级不满足设计要求为例，以工程规范和桩土参数经验取值为依据，提出缺陷桩基处治方案。并详细计算和分析了缺陷桩基处治前后的竖向和水平承载力对比，为该工程处治的设计和施工提供参考依据。

Abstract

Treatment of defect pile is a difficult issue in engineering construction. Taking Dandu Bridge project as an example

in which the concrete strength of pile foundation does not meet the design requirements

and on the basis of engineering specification and empirical values of pile-soil parameters

the treatments of defect pile are proposed. The comparison between the vertical and the horizontal bearing capacities of the defect pile before and after the treatment is analyzed thoroughly; and the analysis can be used as references.
