Basic research to evaluate the vertical stresses and settlements on the subgrade

Various amplitudes and frequencies of axle loads are applied to the domestic conventional line. Vertical stresses and settlements on the subgrade may be changed depending on the variation of axle loads. This paper introduces the research results to estimate vertical stresses and settlements on the subgrade with numerical analysis(Distinct Element Method), full scale test, and field test.
