Abstract: The vacuum mounding preloading method to improve soft ground is a new technique to soft ground improvement.This method is developed from vacuum preloading and mounding preloading.A practical calculation method to predict the settlement in the period of the vacuum mounding preloading has been put forward in this paper to calculate the settlement of the expressway embankment.This calculation method is a amended method of earth preloading method is a amended method of earth preloacling method

Key words: vacuum mounding preloading method, rheological behavior, effective stress, permeability coefficient, consolidation degree, daub range

摘要： 真空堆载联合预压加固软基技术，是从真空、堆载预压方法中发展起来的一种新的软基处理技术。笔者在 对以往计算方法和几条高速公路真空预压软基处理试验工程总结的基础上，提出真空堆载联合预压加固软基的实 用设计方法，对高速公路的软基处理具有参考作用
