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… More >
