摘要
采用Abaqus软件以广州市南沙区典型软土为例,建立平面二维模型,对就地固化技术在道路软土处理中的应用进行研究.研究结果表明,就地固化层具有明显的板体支撑作用,对上部结构荷载应力起到扩散和滞后的作用,有效减少了路基沉降,提高了路堤施工期的稳定性;就地固化技术可有效应用于大于5m的软土路基;就地固化路基路堤预压期满足软土路基的90 天预压要求即可.
Abstract
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.
