摘要
以上海地铁4号线海伦路站附近隧道周围加固软粘土为研究对象,在根据现场监测数据制定室内"多功能循环三轴试验系统"试验的基础上,利用压汞仪微观试验研究方法,对隧道周围加固软粘土微结构进行定量研究.应用热力学关系模型计算分形维数,分析分形维数与荷载之间的关系,得到残余应变随分形维数的变化规律.
With field monitoring and laboratory GDS test and mercury intrusion test,a quantitative study was conducted on the microstructure of the reinforced soft clay around the tunnel near the Hailun Road Station of Shanghai Metro Line 4.The fractal dimension was calculated by the thermodynamic model,and the relationship between the fractal dimension and the vibrational load was analyzed,and the variation law of residual strain with fractal dimension was obtained.
