Dynamic Response of Ballastless Track XCC Pile-Raft Foundation under Train Axle Loads

CODEN: JTEVAB

Abstract

In order to study the dynamic response of ballastless track X-section cast-in-place concrete (XCC) pile-raft foundations under different axle loads, this article presents an experimental study focusing on the dynamical soil stresses and velocity response of a ballastless track XCC pile-raft foundation under vertical cyclic loading. It was found that the dynamic soil stresses on the subgrade surface and the subsoil surface exhibit “ω” and “U” shapes, respectively. The gravel cushion has given an invaluable damping effect to the soil in transmitting velocity to the soil foundation.
