本文从土粒内部结构及软粘土地基受荷后固结的时间效应出发,简述了粘弹性流变模型及粘弹性固结理论的适用性,推导了粘弹性固结问题计算公式,评述了计算所用粘弹性参量测定的方法及存在问题。将某工程的粘弹性理论、太沙基理论的计算沉降值与实际沉降观测值进行了比较后认为,粘弹性固结理论比太沙基固结理论较为接近实际。
In this paper, the viscoelastic rheological model and the viscoelasticity theory are applied to describe the internal structure of soil particles and the time effect of the consolidation of soft clay foundations. The formulas for viscoelastic consolidation are deduced and reviewed. Calculate the viscoelastic parameters used in the measurement methods and problems. Comparing the viscoelasticity theory of a project with the calculated sedimentation value of Taisaji’s theory and the actual settlement observation, it is concluded that the viscoelastic consolidation theory is closer to reality than the Taishaji consolidation theory.
