真空-堆载联合预压法在高速公路软基加固中的应用研究

摘要

Based on the application of the vacuum-surcharge preloading technology in Yong-Tai-Wen Expressway,the reinforcing mechanism and construction process of this technology used in soft soil foundation are introduced here in detail,then its reinforcing effect is explained by some test data.After using this method,the settlement could be quickened,so it is a more effective and suitable method for foundation treatment.%基于真空——堆载联合预压技术在甬台温高速公路的应用,介绍了该方法处理软土地基的加固机理、施工过程,并通过一些观测试验资料来说明加固效果。采用该方法后,加快了沉降速度,同时也说明该方法是一种高效、经济合理的地基处理方法。
