The deformation of a bridge foundation(i.e.pier)of high-speed railway with ballastless track may cause additional irregularities,thereby impacting train operation.By using a unit-slab ballastless trac
Centrifuge model tests were used to simulate pile-raft composite foundation and pile-geogrid composite foundation with different pile spacing for researching the time effect of negative skin friction
This study investigates the application of tire derived aggregate(TDA)mixed with ballast material as an approach for improvement of the ballast track performance.In order to assess the TDA influence o
