列舉了國內外部分防滲墻工程塑性混凝土基本配合比及性能參數；國內自主研發的自凝灰漿墻體材料及應用於三峽工程三期圍堰防滲墻的配合比；固化灰粘土漿、膨潤土漿的物理力學性能及固化灰漿採用不同制攪方法時的配合比。 -
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。
