真空-堆载联合预压加固高速公路软基的实用设计

Practical design method to the vacuum-mounding combined preload on expressway embankments

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 。

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 and it has been certified by several experiment embankments.It is useful to development the vacuum mounding preloading method.
