The Exploration and Research of CRTS I Slab Ballastless Track Used in the Freight Lines
Applied Mechanics and Materials, 2012The CRTSⅠslab ballastless track structure was the research object of this thesis and the truck vehicle-track dynamics coupled model had established in this thesis. Germany track interference spectrum was used as the track irregularity. The study analyzed the force conditions of the CRTSⅠslab ballastless track under the action of heavy freight trains in

The Research on Dynamic Characteristics of Ballastless Track Slab on 32m Simple Box Girder
2010 International Conference on Intelligent Computation Technology and Automation, 2010According to the fact that the ballastless track system study results often deviate from the actual value greatly using the method of simplified box girder in the high-speed railway at present. The new overall 3D models with simple box girder and ballastless track slab are built by using ANSYS software, and dynamic response results of ballastless track

Study on the Resistance to Water of CA Mortar Used in CRTSII Ballastless Slab Track
Applied Mechanics and Materials, 2014This paper studied mechanical properties and microscopic changes of CRTSⅡtype CA mortar under the roles of the conditions of water immersion, acid soaking, wet and dry cycling, etc. The results show that: under the role of water immersion, the relative compressive strength decreases and elastic modulus decreases firstly and then increases with the ...

Design method of pile-slab structure roadbed of ballastless track on soil subgrade
Journal of Central South University, 2013Pile-slab structure roadbed is a new form of ballastless track for high speed railway. Due to lack of corresponding design code, based on the analysis of its structure characteristics and application requirements, it is proposed to carry out load effect combination according to ultimate limit state and serviceability limit state, and the most ...

Finite Element Analysis of Ballastless Track Rail-Floating Slab’s Dynamic Characteristics
Applied Mechanics and Materials, 2010By using the finite element analysis software ANSYS, a three-dimensional dynamic finite element model of ballastless track rail –floating slab was established. The model takes into account of the track irregularity case, the analysis the dynamic response characteristics of the rail and floating slab under the vertical force in the track structure.

Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics
Determining temperature load values for slab ballastless tracks in cold-temperate climates is essential for assessing track performance. Using historical meteorological data from the Shenyang-Baicheng high-speed railway and heat transfer principles, a thermal model for the CRTS III slab ballastless track was developed to analyse temperature field ...
