水泥土搅拌桩在立交桥引道地基加固中的应用

Application of cement-deep-mixing pile in subsoil of bridge approach

通过讨论水泥搅拌法加固软土地基处理方法 ,提出了解决地基承载力不均及整体性差和由此造成的立交桥桥头跳车问题的解决方法 。

Cement deep mixing method is discussed in this paper to solve non uniformity of bearing capacity of the subsoil and the problem of vehicle jumping at the bridge approach. With a practical case of soil treatment at the bridge approach of certain overpass, the paper introduces the construction and detection techniques of interlocking cement deep mixing pile.
