The research indicate that the structured soft clay has below several characteristic, the viscous strain is produced during the stage of primary consolidation and of second consolidation, and in the prophase, the relation of stress - strain - strain rate is unique, so the form of constitutive model, such as, f ( v ', e ) = 0, f ( ' v, e, t ) = 0, ca n ' t describe strain behavior of soil skeleton rationally ; the time - dependent properties involve three aspects, in addition the time - dependent strain, apparent preconsolidation pressures that depend on strain rate, and the effect of creep compression on apparent preconsolidation pressures ; because of holding structural strength, the mechanics characteristic is determined by the magnitude of stress, and the compression curve is composed of several sections. by combining structural yield stress and it ' s characteristics with the improved time line model, a new one - dimensional elastic visco - plastic consolidation model is established
研究結果表明，結構性土的固結過程具有以下特性：主固結和次固結階段都包含有因土骨架的粘滯性移動而產生的變形，而且在正常固結階段，存在應力?應變?應變速率的唯一性， f （ _ v ， e ） = 0 、 f （ _ v ， e ， t ） = 0形式的本構關系不足以描述土骨架的變形行為；固結壓縮過程中的時間效應包括三個方面的內容，除了應力應變關系與時間相關外，還包括粘滯性變形引起表觀前期固結壓力增加和屈服應力的應變速率效應；軟土的結構性使其力學特性與應力水平相關，壓縮曲線具有分段性。 -
Using 3d 20 - node iso - parameter, 3d 12 - node infinite element and 3d 16 - node interface element, a coupled numerical approach for pile group - soil system under lateral loads is set up. a corresponding three - dimensional, nonlinear and elastic - plastic program ( epagpll ), include two materials and four nonlinear constitutive relations, is worked out by fortran 90 computer language. in the analysis the nonlinear e - model, k - g model and cambridge model with two yield surfaces are employed in the analysis of near - field soil, and the nonlinear analysis method is used in the piles - soil interface and distant - field soil
