真空联合堆载预压法在市政道路软土地基加固中的应用

The Application of Vacuum-piled-load Preloading Method in Soft Soil Foundation Reinforcement of Municipal Roads

天然软土地基具有流变性强、孔隙比大、含水量高的特点,为保障市政工程施工质量,需充分利用好软土地基加固技术。文章以某市政道路工程为例,对该工程软土地基加固施工中所采用的真空联合堆载预压法进行分析,阐述了具体的施工方法。通过软土地基加固效果检测发现,加固处理后的软土地基土体含水率与孔隙比有所下降,能够加快土体固结,说明此次软土地基加固效果良好。

Natural soft soil foundation has the characteristics of strong rheology,large porosity ratio and high water content.In order to ensure the construction quality of municipal engineering,it is necessary to make full use of soft soil foundation reinforcement technology.Taking a municipal road engineering as an example,this paper analyzes the vacuum-piled-load preloading method used in the engineering soft soil foundation reinforcement construction,and expounds the specific construction method.Through the inspection of soft soil foundation reinforcement effect,it is found that the water content and porosity ratio of soft soil foundation after reinforcement treatment decrease,which can accelerate soil consolidation,indicating that the soft soil foundation reinforcement effect is good.
