| 摘 要： | 以河南某地灰粘土的室内流变试验的试验结果为例,介绍了利用土体的流变曲线确定其流变本构模型和模型参数的过程;对土体的粘弹塑性流变问题进行了有限元分析;编制了考虑土的流变特性的深基坑支护桩有限元计算程序,进行了实例计算,对计算结果进行了分析,并与实测值进行了对比;结果表明,实测值与考虑流变时的理论计算值比较吻合.

| Abstract: | On the basis of the results obtained from the soft-soil laboratory rheologic test in Henna province,it introduces the obtaining of rheology constitutive model and rheology parameters from the rheology curves. The finite element analysis of viscoelasto-plastic rheology of soil is done. And the programme which is able to carry out the finite element calculation of deep foundation pit bracing-stake with the consideration of the soil's rheologic characters is developed and the example resolved by the programme is listed. The analysis concerning the results of deep foundation pit is given. The calculated result and the factual result are also compared. |
