高速公路工程软土地基处理技术

Soft Land Foundation Treatment Technology of Highway Engineering

在高建公路工程建设中,不可避免地会遇到不同类型的地基,软土地基就是最常见的特殊地基之一。软土地基具有含水量高、孔隙比大、抗剪强度低的特点,需要经过逐当的处理才能作为高建公路路基,因此,必须结合实际工程的具体情况,选择合适的软基处理技术,把提软基处理技术的关键点,以确保软基处理的科学性、规范性和可靠性。基于此,介绍了高迄公路工程软基处理的常用技术方法,分析了置筷法、固化法、堆载预压法等关键技术,同时阐述了不同软基处理技术的要点,提出了高速公路建设中软基处理的注意事项。

In the construction of expressway cngincering,we will inevitably encounter diferent types of foundation,and the soft land foundation is one of the most common special foundation.Soft land foundation has the characteristics of high water content,large pore ratio and low shear strength,which needs to be properly treated as a highway subgrade.Therc-fore,it is necessary o combine theactual speifiestuation of the engincering,select the appropriate soft foundation pro.cesin echnolgy,gra th key pints f of foundtion prcesig echoloy to ensure the cietifi,normative and reliability of soft foundation processing.Based on this,the common technical mecthods of soft foundation treatment in ex-presway engineering are introduced,the replacement method,curing method,stacking prepressing method and other key technologies are analyzed,and the key points of different soft foundation treatment technologies are alsoexpounded,and the precautions of soft foundation treatment in expressway construction are proposed.
