钢管内支撑在复杂条件深基坑的应用

On application of inner support of steel pipe in deep foundation pits with complicated conditions

以富佳苑二期工程为例,介绍了钢管内支撑在复杂条件深基坑中的应用实践,对基坑支护设计和钢管内支撑施工工艺进行了具体阐述,并对支护结构的监测方法作了简要说明,为今后同类项目施工积累了一定经验。

Taking Fujiayuan secondary project as the example,the paper introduces the application of the inner support of steel pipe in the deep foundation pits with the complicated conditions,illustrates the design of the support of the foundation pits and the construction craft of the inner support of steel pipe,and indicates the supervision methods for the support structure,so as to accumulate certain experience for the similar projects.
