摘　　要：通过加宽路基新技术的现场实测试验,研究了加宽高速路加宽填土施工过程及工后一段时间,原有及加宽路基、地基的变形发展规律,实验表明,原有路基的水平位移先负后正;地基的变形与加宽路基的地基处理方式有关.结论得到了工程实测数据的验证.　Two groups of composite foundation experiments are carried out to simulate the working mechanism of widening highways foundation.The deformation tendency of soil and highway foundation during and after the soil filling-in process is measured.The experiments results show that the horizontal displacement is firstly negative and then positive.The road bed deformation is related to the forms of soil enhancement.Conclusions of the project measured data validation.
