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。 Defective pile foundation treatment is a common difficult problem in engineering construction. Taking the design requirements for the strength of pile foundations in Dujian Bridge Project as an example, based on the engineering norms and empirical values ​​of pile and soil parameters, the treatment scheme of defective pile foundation is proposed. The vertical and horizontal bearing capacity of the damaged pile foundation before and after treatment are calculated and analyzed in detail, which provides a reference for the design and construction of the project.
