大面积填土的地基处理和桩基设计

Foundation treatment and pile foundation design for large-area filling

介绍了上海某项目的地基基础设计情况。针对场地内大面积填土引起的地基土沉降,采取了具体的计算分析和针对性施工措施。桩基设计中对填土造成的负摩阻力做了具体的分析,桩基设计按高承台桩进行设计。提出设计中应引起重视的问题,可作为同类基础设计的有益参考。

The foundation design of a project in Shanghai was introduced. In view of the settlement of foundation soil caused by large-area filling in the field,concrete calculation analysis and construction measures were taken. In the design of pile foundation,the negative frictional resistance caused by earth fill was analyzed concretely,and the design of pile foundation was designed according to the high pile cap. The problems in the design which should be paid attention were put forward,which can serve as a useful reference for similar basic design.
