泥岩地质条件下自平衡法试桩技术的应用

Application of pile-testing technology with self-balanced test method under mudstone geological conditions

以河口黄河大桥工程为例,基于自平衡法测试原理,并利用工程桩进行了试桩,得到了泥岩地质条件下基桩的极限承载力、桩侧摩阻力、桩端阻力及分担情况等数据,可为同类地质条件下桩基设计提供参考。

Taking Yellow River bridge engineering in Hekou as an example,based on self-balanced testing principles,the paper carries out pile test by applying the engineering pile,and obtains the ultimate bearing capacity,lateral pile friction resistance,pile tip resistance and sharing conditions of foundation pile under mudstone geological conditions,which will provide some guidance for pile foundation design under similar geological conditions.
