摘要
为解决路基工程中难以开展动态回弹模量测试的难题,文中采用承载板法测量路基的静态回弹模量,采用PWFD测量路基的动态回弹模量,通过线性回归拟合得到路基的静态和动态回弹模量的预估模型,并建立路基的静态和动态回弹模量的转换关系。
It is difficult to test the dynamic modulus of resilience of the subgrade in engineering.The bearing plate method is used to measure the static modulus of resilience of the subgrade,and the PWFD is used to measure the dy⁃namic modulus of resilience of the subgrade.The estimation model of the static and dynamic modulus of resilience of the subgrade is obtained by linear regression fitting,and the conversion relationship between the static and dynamic modulus of resilience of the subgrade is established.
