水泥搅拌桩复合地基承载力研究

Research on the Bearing Capacity of Cement Treated Composite Foundation

根据室内模型试验和现场载荷试验，对水泥搅拌桩复合地基承载力的确定进行了分析，证明从提高承载力角度来说，过分增加桩长是无意义的，桩长主要是用来控制变形。对水泥搅拌桩复合地基承载力的确定和优化设计提出了建议。

The determination of the bearing capacity of cement treated composite foundation is studied by conducting model test and field bearing test.Results show that the length of cement treated column is mainly determined by the permissible settlement. The excessive length of column has no use for enhancing the bearing capacity of the column. Finally, Suggestion of the design of cement treated composite foundation is presented.
