摘要
在滨海软土地基中,基岩埋深浅、淤泥厚度大等复杂地质条件,对基坑支护的变形及稳定提出了严苛的要求。以厦门市某复杂环境下不对称基坑工程为例,该工程采用咬合灌注桩+1道钢筋砼内支撑的支护方案,采取全套管咬合工艺成桩和非对称土方开挖工序。监测结果表明,该基坑支护结构能很好地控制对周边环境的变形。
In the coastal soft soil foundation,the complex geological conditions such as shallow bedrock buried depth and large silt thickness put forward strict requirements for the deformation and stability of excavation.Taking the deep foundation pit project in Xiamen as an example,the support scheme of secant pile+1 reinforced concrete internal support is adopted.The whole casing biting process is adopted in the pile forming process,and the asymmetric excavation process is adopted in the excavation.The final monitoring results show that the support structure plays a good role in controlling the deformation of the surrounding environment.
