Construction issues of high-speed rail infrastructures have been increasingly concerned
worldwide, of which the subgrade settlement in soft soil area becomes a particularly critical …

To date, the application of self-sensing or other structural health monitoring (SHM)
technologies in railway sleepers is limited. Development and deployment of smart sleepers …

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

High-frequency train loads and complex environmental factors over a long period will
inevitably cause subgrade settlement, an issue that adversely affects line smoothness. The …

Railway infrastructures have played a critical role to ensure the continuity of goods and
passenger transportation in China. Under extreme loading and environmental conditions …

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 …

Track degradation and defects of existing passenger and freight mixed railroads are
concentrated in bridge–embankment transition zones. Heavy axle load (HAL) operation on …

In the French conventional railway substructure, the interpenetration of ballast grains and
subgrade fine soils that occurred over years of operation has created a new layer, namely …

Full-scale laboratory-based testing is used to compare the long-term settlement performance
of a precast concrete slab track section to a ballasted track (with concrete sleepers) resting …

Excessive uneven settlements of railway subgrades will reduce the durability of ballastless
slab track and jeopardize the train operation safety. In this paper, a technology by injecting …
