| Abstract: | This paper introduces the method of secondary deformation modulus EV2 tests with the bearing plate having 400 mm and 600 mm in diameter respectively. Through analysis of on site test data from the subgrade construction of Beijing Shanghai high speed railway and Beijing Shijiazhuang Passenger dedicated Line，the relationship between test results of secondary deformation modulus EV2 tests with the bearing plate having 300 mm,400 mm and 600 mm in diameter respectively is obtained，at the same time，the effect of maximum filling material size on these test results is discussed. |
