Priest TITLE The role of clay content on the response of railway track foundations during free-to-drain cyclic changes in principal stress rotation JOURNAL Transportation Geotechnics PAPER DOI This dataset contains: The figures are as follows: Fig. 1 Volumetric strain accumulation for materials A, B, C and D (7%, 11%, 14% and 24% clay) in free-to-drain conditions during test stage (a) at a cyclic shear stress 񎓊z = 8.5 kPa and during test stage (b) at a cyclic shear stress 񎓊z = 11.5 kPa Fig. 2 The effect of increasing the intergranular (a) (b) and global (c) void ratios on the plateau volumetric strain of the sand / clay mixes in free-to-drain conditions during test stage (a) at a cyclic shear stress 񎓊z= 8.5 kPa and during test stage (b) at a cyclic shear stress 񎓊z = 11.5 kPa Fig. 3 Excess pore pressure accumulation at the furthest point from the drainage boundary for materials A, B, C and D (7%, 11%,14% and 24% clay) in free-to-drain conditions during test stage (a) at a cyclic shear stress 񎓊z = 8.5 kPa and during test stage (b) at a cyclic shear stress 񎓊z = 11.5 kPa Fig. 4 4 Resilient stiffness changes for materials A, B, C and D (7%, 11%, 14% and 24% clay) during test stage (a) at a cyclic shear stress 񎓊z = 8.5 kPa and during test stage (b) at a cyclic shear stress 񎓊z = 11.5 kPa Date of data collection: 01-10-2009 to 30-09-2013 Information about geographic location of data collection: University of Southampton, U.K. Licence: Creative Commons Attribution 4.0 International (CC BY 4.0) https://creativecommons.org/licenses/by/4.0/ Related projects:The research was funded by the Engineering and Physical Sciences Research Council (EPSRC) through the Programme Grants Track21 (EP/H044949) and Track to the Future (EP/M025276), with support from Network Rail through the Strategic Collaborative Research Framework in Future Infrastructure Systems.
