Test shows that the instantaneous displacement presents obvious nonlinear property, and the creep deformation of soil is related to pore-pressure dissipation. The influence of creep on stress and strain is decided by drainage condition of soft foundation.
本文还对深圳海淤土做了蠕变试验，从中可以看出软土蠕变的基本规律，软土瞬时变形呈现明显的非线性，软土蠕变变形和超静孔压的消散有关，它对应力和应变的影响取决于土体的排水条件，排水条件不良时，蠕变影响大。
参考来源 - 软土的蠕变—固结特性及软土地基固结有限元分析The deformation course of soft soil is actually the process of consolidation and creep concurrently. The ratios of two deformations to total deformation depend on many factors,among which stress level and drainage condition are the most important.
研究结果表明:软土变形的时效性产生于固结特性和蠕变特性的耦合效应,土体的变形过程实际是固结和蠕变共同作用的过程,任一时刻两种变形在总变形中所占比例取决于多种因素,其中最重要的是应力水平和排水条件。
