The study shows that besides boundary conditions , the factors influencing the nonlinear consolidation behavior of soils are the compression index cc , the permeability index ck , the level and the rate of loading , and the thickness of soil , etc . in nonlinear consolidation , especially for layered soils , the average consolidation degree defined by settlement , us is greater than the one defined by effective stress , up , i . e . , the rate of the development of settlement is greater than that of the dissipation of excess pore water pressure 研究表明,除邊界條件外,影響軟土地基一維非線性固結性狀的主要因素是壓縮指數c _ c 、滲透指數c _ k 、荷載大小與加荷速率、土層厚度等。對于非線性固結,特別是成層地基,按沉降定義的平均固結度u _ s大于按有效應力定義的平均固結度u _ p ,即沉降發展速率要快于超靜孔壓消散的速率。
