ABSTRACT = {This paper reports the experimental study of water pressure properties inside 
crack of Non-ballasted track structure. Pre-existing crack concrete specimens 
with 510 × 1290 × 80mm dimensions were produced, and fluid-fracture 
interaction tests under cyclic loading were performed. The water pressure were 
measured at different locations inside cracks and with different loading
frequencies as well as amplitudes. By using the experimental data, then is 
employed to investigate the water pressure distribution inside cracks affected 
by both the frequency and amplitude under cyclic loading. From this study, it 
was determined that the water pressure of cracks alternates between positive 
and negative values under cyclic loading, and increase with the increase of 
crack depth, loads amplitude and loads frequency. Furthermore ， the
relationship between the water pressure, loads amplitude and loads frequency 
can be fitted into a polynomial expression.},
