Finite layer analysis of three-dimensional biot consolidation of homogeneous soils

Abstract

建立了三维横观各向同性土体固结的有限层求解方法 ,并编制了相应的计算程序 ;通过 2个算例的分析对比 ,验证了计算方法和程序的正确性 ;探讨了横观各向同性地基参数对三维地基固结的影响 ,给出了对工程有价值的相关计算图表和结论。 This paper presents a finite layer procedure for the consolidation analysis of layered soils using a cross isotropic elastic constitutive model. The program is first verified using two published results. Then using this program,the influences of cross isotropy on the consolidation behavior are analyzed. The results obtained using the cross isotropic elastic model are compared with results using isotropic elastic model. It is found that the cross isotropy has very large influences on the consolidation behavior. Curves of the average degree of consolidation are obtained and presented in the paper,which is useful for engineering practice.
