Experimental Study and Numerical Analysis of Structural Performance of CRTS II Slab Track under Extreme High Temperature

open access: yesAdvances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
A ballastless track is susceptible to damage and even failure of structural components under the long‐term effects of extremely high temperatures. In this paper, considering the influence of different constraint boundaries, a 1 : 4 scaled model of a ballastless track‐bridge structural system was produced and placed in a large‐sized environmental ...

Numerical Research of Lightweight Foam Concrete Replacement Method of Deep Soft Foundation Treatment of Low‐Filled Embankment

open access: yesGeofluids, Volume 2022, Issue 1, 2022., 2022
A new method of replacing soft soil with lightweight foam concrete (lightweight foam concrete replacement method, LFCRM) is carried out to treat deep soft foundation under the low‐filled embankment. Two‐dimensional models with different thicknesses of replacement are established by the finite element platform (MIDAS/GTS).

Transverse Oscillation of a Base Slab Section of Ballastless Track

open access: yesWorld of Transport and Transportation, 2019
The study is devoted to construction of a mathematical model of a slab of a ballastless base of a railway track, assembled from separate segments fastened together. Each rectangular segment is modeled by a transversely isotropic prestressed plate. An equation has been obtained that allows researchers to study the natural oscillation frequencies of a ...
