Geomaterials exhibit elastoplastic behaviour during dynamic and repeated loading
conditions. These loads are induced by the passage of a train or vehicle which then …

Traditional ballasted tracks have been used intensively around the world with ballast as the
main material for tracks. Ballast has a significant contribution to the track alignment, stability …

Abstract Model testing in laboratory, as an effective alternative to field measurement,
provides valuable data to understand railway׳ s dynamic behaviors under train moving …

In recent years, the high development of high-speed railway lines cross through areas with
poor geological conditions, such as soft soil, offshore and low-lying marsh areas, resulting …

An iterative procedure for numerical prediction of long-term degradation of railway track
geometry (longitudinal level) due to accumulated differential settlement of ballast/subgrade …

To predict long-term track degradation of ballastless track due to evolution of differential
subgrade settlement in high-speed railway, an iterative approach is put forward. A detailed …

Principal stress rotation induced by moving loads from trains significantly influences railway
track settlement accumulation. The stationary cyclic loading commonly adopted to study …

近年来, 随着交通和能源基础设施建设的快速发展, 循环动载引起的工程问题使得土动力学与岩
土地震工程的研究面临许多新的课题. 文章简要评述土动力学与岩土地震工程在国内外的研究 …

To study the adaptability of cement-improved expansive soil as a heavy-haul railway
subgrade filling material, based on a test section of the Inner Mongolia-Jiangxi railway …

The geometry of a ballasted railway gradually deteriorates with trafficking, mainly as a result
of the plastic settlement of the track-bed (ballast and sub-base). The rate and amount of …
