| Description | Journal: Iop Conference Series: Earth and Environmental Science The compaction quality of subgrade is controlled by such indexes as high speed railway coarse soil subgrade adopts foundation coefficient K$ _{30}$, second deformation modulus E$ _{ v2}$ and dynamic deformation modulus $E_{vd}$ , but the three detection principles are similar. For the purpose of reducing the detection workload and improving the detection efficiency, based on a brief analysis of the test principles of the three indicators, this paper carries out the filling and testing of coarse grained soil subgrade, obtains the values of 10 groups of K$ _{30}$, E$ _{ v2}$ and $E_{vd}$ , and analyzes the correlation of K$ _{30}$, E$ _{ v2}$ and $E_{vd}$ . The results shows that both K$ _{30}$ and E$ _{ v2}$ have a good linear relationship with $E_{vd}$ and establish a corresponding functional relationship. The quality inspection scheme for coarse grained soil subgrade filling indirectly judged by the dynamic deformation modulus $E_{vd}$ and the secondary deformation modulus E$ _{ v2}$ is proposed. |
