摘要
结合工程实例,介绍泡沫轻质土对软弱地基的加固方案,并根据地下水腐蚀强度进行地基承载力和沉降量验算。结果表明,泡沫轻质土超挖换填软弱地基,不增加附加应力,工后沉降为0,考虑地下水腐蚀影响时,通过素填土层厚度控制超挖深度,地基承载力和工后沉降均能满足规范要求,为表层素填土下卧软弱淤泥层场地地基处理的方法应用提供了借鉴。
Combining with the practical project, this paper presents the scheme of foamed mixture lightweight soil in soft soil foundation treatment. According to the groundwater corrosion strength, it calculates the subgrade bearing capacity and settlement. The results show that it will not increase the additional stress and settlement after construction. Considering the influence of groundwater corrosion and controlling the depth of over excavation by the plain fill thickness, both the foundation＇s bearing capacity and settlement after construction can meet the requirements. It provides a reference for soft soil foundation treatment.
