摘　　要：我国地域广阔,地质情况极为复杂,其中软土在我国分布广泛,给公路工程施工带来了严重的不利影响,成为公路工程施工必须处理的病害问题。长期以来,在公路软基处理中往往选取堆载预压法、复合地基法等,但随着技术要求的不断提高,此类处理方法已经与当前施工要求不符,真空排水预压施工技术作为一种新型软土地基加固专利技术,将其广泛地应用于公路软基施工,可提高施工稳定性、缩短工期及有效处理工后沉降,是当前软基加固的主要技术之一。为此,本文在充分掌握真空排水预压加固机理的基础上,结合具体工程案例,对其施工工艺等内容进行了分析与探究。China is vast with complex geological condition.The soft soil is widely distributed in China,which exerte an adverse impact on highway construction and become the problems to be dealed with of highway construction.The preloading method and composite foundatio are often used in the treatment of highway soft foundation for a long time.But with the increasing technical demands,these methods are not consistent with the current construction requirements.The vacuum drainage preloading construction patent technology,as a new type of soft soil foundation reinforcement technology,is widely used in highway soft foundation construction.It can improve the stability of construction,shorten the construction period and effectively handle the settlement after construction.Based on the full grasp of the vacuum drainage preloading mechanism,this paper give an analysis on the construction technology,combined with the specific project case.
