| 摘 要： | 基于软土结构性分析,提出一个扰动度的概念,建立扰动度与再压缩指数、压缩指数、次固结系数和表观前期固结压力等土工参数之间的定量关系,并将此关系用于结构性软土一维弹粘塑性固结分析中,说明压缩曲线各段对固结过程不同阶段的影响,以及在沉降预测中,室内试验的土工参数校正和考虑粘滞性效应的重要性. |

| Abstract: | Based on the analysis of soft soil structure properties,a new concept of degree of sample disturbance is put forward,and the quantitative relation between the degree of sample disturbance and civil parameter,such as the re-compression index,the compression index,the coefficient of secondary compression,the apparent pre-consolidation pressure etc,are established.By using the quantitative relation to a one-dimensional elastic visco-plastic consolidation model,the significance of the correct coefficient and viscous effect is presented. |
| Keywords: | soil structure properties disturbance quantitative relation elastic visco-plastic consolidation |
