通过三轴流变试验仪,以原状土样与重塑土样为试验材料,对吹填软土流变历时特性进行了研究。研究结果表明:结构性对土体流变特性有明显影响。结构性的存在,使得原状土流变破坏峰值高于重塑土;当应力低于结构屈服应力时,由于结构性的作用,抵抗变形能力强,使原状土流变趋于稳定的时间要小于重塑土;当应力高于结构屈服应力时,随着结构的破坏,其流变历时特性逐渐向重塑土靠拢,最终趋于一致。 By means of triaxial rheometer, undisturbed soil samples and remolded soil samples were used as experimental materials to study the rheological characteristics of dredged soft soil. The results show that: the structure of the soil rheological properties have a significant impact. The existence of structure makes the peak value of undisturbed soil rheological damage higher than that of remolded soil. When the stress is lower than the yield stress of structure, due to the structural effect, the resistance to deformation is strong, and the undisturbed soil rheological stability tends to be less than Remodeling the soil; when the stress is higher than the structural yield stress, with the destruction of the structure, its rheological diachronic characteristics gradually move closer to the remodeled soil and eventually converge.
