    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 More >
