Research on the Application of In-situ Solidification Technology for Soft Soil Treatment in Road Construction
Employing Abaqus software,this study constructs a two-dimensional planar model based on the representative soft soil found in Guangzhou's Nansha District to investigate the application of in-situ solidification technology in roadbed soft soil treatment.The findings demonstrate that the in-situ solidified layer provides substantial slab-like support,diffusing and postponing the load-induced stress from the upper structure,thereby markedly diminishing subgrade settlement and augmenting the stability of the embankment during construction.The research confirms that in-situ solidification is an effective method for treating soft soil subgrades deeper than 5 meters and the solidified roadbed meets 90-day preloading requirement for such subgrades.
