湿陷性黄土广泛分布于我国的西北、东北、华中及华东等地区,其主要是由于上覆土层在浸水后结构性早到破坏而发生显著的附加变形。在湿陷性黄土分布的地区进行工程建设,极有可能因为地基实现而引起附加沉降,从而给建筑工程造成很大的危害。因此,在湿陷性黄土地基上进行工程建设时一定要掌握地基处理的方法,并明确施工时的注意事项。本文主要总结了西安至平凉线这一工程建设中湿陷性黄土路基的地基处理方法,并对这几种方法在实施的过程中需要注意的问题进行简单总结,进而分析处理这些方法实施过程中问题的处理要点。
Collapsible loess is widely distributed in the northwestern, northeastern, central and eastern China and other regions, mainly due to the obvious additional deformation of the overlying soils caused by structural early damage after soaking. Construction projects in areas with collapsible loess areas will most likely cause additional settlement due to the foundation being realized, thus causing great damage to the construction projects. Therefore, when constructing a project on collapsible loess foundation, it is necessary to know the method of foundation treatment and to clarify the precautions during construction. This paper mainly summarizes the foundation treatment methods of collapsible loess roadbed in this project from Xi’an to Pingliang Line and briefly summarizes the problems needing attention in the implementation of these methods and then analyzes and processes the implementation of these methods The key points of the problem
