根据工程实践和软土结构性试验，建立了以结构屈服应力为界的两段软土结构性模型。建立了均匀结构性软土地基一维固结模型。在推导公式时，考虑了土的结构特性。分析了土体结构性和扰动对固结的影响。研究结果表明，随着孔隙水压力的消散，土体结构性破坏并向沿着扩展，上部土体的固结对下部土体的固结沉降起抑制作用，扰动减缓了地基的沉降。土的结构性对固结的影响显著。
Based on engineering practice and structural experiments of soft clay, a 2subsections model bounded by structural yield stress of Cvp and kp curves were developed. A 1D consolidation model for uniform structured soft foundation was set up. In deriving the formula, the soil structure characteristics were considered. The influences of soil structure characteristics and disturbance on the consolidation were also analyzed. The results of case study showed that the soil structures would destroy and extend to underside along with dissipation of pore water pressure, the consolidation of upper soil would restrains the consolidation settlement of nether soil and disturbance would slow down the settlement of foundation. The influence of soil structure characteristics on consolidation was notable.
