水泥土桩复合地基的流变分析

Rheologlcal analysis of cement-soils composite foundation

应用流变力学理论建立了一种能同时反映水泥土桩复合地基固结、次固结的流变模型 ;应用 ANSYS有限元程序 ,结合尹中高速公路工程实例 ,对导出的公式和所建立的模型进行了工程验算 ,证明导出的公式和所建立的模型及软件合理 。

A rheologieal model, which reflects both consolidation and secondary consolidation settlement, is suggested. On the base of ANSYS program,the deduced formula and the found model for rheological analysis of cement-soils composite foundation is checked.As an example,the engineering project,YinZhong highway,was analyzed.Some useful regulations are concluded from the data.
