基坑深层搅拌桩与土钉墙复合支护实例

本文介绍了某地区信息大厦工程的基坑支护方案。施工单位根据该工程的地质情况、基坑深度和周边环境,设计出双排深层搅拌桩结合土钉墙复合支护的结构型式。通过这一个成功的施工实例,证明了在淤泥层和砂层较厚、地下水位较高的不利地质条件区域,基坑采用这种复合式支护的型式,是较稳妥的方案。

Application of Deep Foundation Pit Mixing Pile and Composite Palification Support

In this paper, a successful foundation support method of a Xinxi Building is introduced. Construction company has designed a double-pole deep foundation mixing pile which combinates the composite palification on accordance with the geological situation, foundation depth and the surroundings of the project. And this construction method has been proved to be a better one used in a bad geological condition region with thick silt stratification, thick stratum of sand and high groundwater level.
