摘要
结合武广客运专线复合地基处理的实际,对武广线岳阳段CFG地基处理的施工工艺与效果进行检测.结果表明,对该段松软土采用长螺旋泵送混合料的CFG处理方式是合适的,桩底能够达到设计要求的持力层深度;成桩过程中,桩体质量能够得到保证,处理后的地基承载力与沉降能够满足无碴轨道对路基要求.
According to the practice of foundation treatment in Wu-Guang passenger dedicated line,the treatment process and quality inspection of CFG pile foundation were analysed in Yueyang section.The analysis results show： the measurement for treating the soft foundation is reasonable with long spiral dill to pump the mixture and the toe of pile,which can reach the necessary depth.In the course of pile formation,the quality of pile could be guaranted.And after the treatment,the bearing capacity and settlement of the foundation can meet the requirements of ballastless track foundation.
