| 摘 要： | 通过对单个交通荷载作用下路面结构体系的数值模拟,计算了路基中竖向动应力的变化,并采用室内动三轴试验研究了软土地基在循环荷载作用下累积变形的规律;通过对以上两项研究的结合,建立了交通荷载作用下软土地基残余变形的计算方法,并计算了不同类型的交通荷载引起的软土路基的残余变形量.

| Abstract: | 3D numerical simulation is adopted to analyze the dynamic response of highway under single loading circle,and to calculate the stress in the roadbed.By a series of triaxial dynamic tests,the relation between residual deformation of soft soil and numbers of loading cycles is proposed.On the basis of the above studies,a method is set up to calculate the residual deformation of soft foundation under vehicle load,and road surface settlements under different vehicle load are analyzed. |

| Keywords: | vehicle load soft road foundation residual deformation |
