摘要:
阐述了用邓肯-张模型以及Biot固结理论编制的解决空间轴对称固结问题的有限元程序,并结合原位测试成果,对超长水泥土搅拌桩复合地基的固结变形、孔隙水压力的分布以及桩身荷载的传递规律等基本性状进行研究的一些成果,对同类工程的设计和施工有较大的指导意义.
Abstract:
The paper focuses on researching the deformation and consolidation behavior of a composite ground with super-long soil-cement columns by FEM. On account of the small vertical deformation and the good quality of the columns, much of the load was transformed to their tips and then to the bearing layer. Thus the theory of effective length should be modified for these columns.
