| Abstract: | On the basis of the results obtained from the soft soil laboratory rheologic test in Henan Province, the obtaining of rheology constitutive model and rheology parameters from rheology curve is described. 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 rheogical characters, is developed; and in 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.The result shows that the calculation results of the lateral displacements are in good agreement with their measured values relatively. |
| Keywords: | rheology deep foundation pit finite element method constitutive model |
