英文摘要	Through the on-site filling test in the subgrade test section of Lanzhou-Xinjiang Railway two-line in desert area, the relationship between dynamic deformation modulus Evd and subgrade filler as well as the compaction quality of the filler is analyzed, which shows a lack of correlation between Evd and K-30 (ground coefficient), while E-vd is well correlated to E-v2 (static modulus of deformation). After analyzing the influence factors of E-vd by combining the numerical calculation of ADINA (three-dimensional dynamic finite element software) with field test, the findings indicate the following conclusions. Complete linear correlation exists between E-vd and Ed(dynamic modulus) in theory, their correlation formula has something to do with dynamic angle of internal friction and dynamic cohesion. When the filler dynamic cohesion keeps low, E-vd increases with the dynamic cohesion and dynamic angle of internal friction; while E-vd will not change with them when the filler dynamic cohesion is large enough. Also, E-vd relates to the shearing strength of soil under the impact load. With Ed stays established, E-vd increases with the shearing strength which is relatively low, but when the shearing strength reaches a certain value, E-vd will no longer change.
