公路软土地基工后沉降预测分析

软土地基沉降是公路建设中的关键问题。该文介绍了工程中广泛采用的以一维变形假定为基础的分层总和法，以及土体参数一维反演分析方法，并结合某高速公路路基工程实例进行工后沉降预测分析。计算结果表明，采用真空联合堆载预压加固软土地基可以大大减小软基的后期沉降。

Analysis of Forecast on Settlement of Highway Soft Soil Subgrade after Construction

The settlement of the soft soil subgrade is the key issue in the highway construction. The article introduces the summation method in layers taking one-dimensional deformation assumed as the base widely applied in the projects,and the earth parameter one-dimensional inversion analyzing method. And combined with the roadbed engineering example of an expressway,the article carries out the settlement forecast analysis after construction. The calculation result makes clearly the use of the vacuum integral heape...
