| 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-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. |
