RESEARCH EXPERIENCE
SOWMIYA CHAWLA 3
ABSTRACT: Railroad track is one of the few geosynthetic applications where a geosynthetic is used
for multiple functions, namely, reinforcement, separation, filtration and drainage. Static and cyclic tests
were performed on full panel railway track models laid on compacted soil subgrades. Tests were
performed on model tracks with two different thicknesses of subballast layer and laid on two different
subgrade soils, namely, Dhanaury clay and Delhi silt. Model tracks were adequately instrumented to
record induced stresses and displacements in the track. Model tracks were reinforced with geogrid or
geotextile or both at suitable interfaces. Track condition after a heavy rainfall was simulated. The
models reinforced with geogrid at ballast-subballast interface were found to be more effective in
reducing the tie displacements, ballast and subballast strains, and subgrade displacements as compared
to the models reinforced with geotextile at subballast-subgrade interface for tracks with Dhanaury clay
as subgrade. On the other handed, the models reinforced with geotextile gave better performance in
terms of reduced tie and subgrade displacements as compared to the models reinforced with geogrid for
tracks laid on Delhi silt subgrade.
Finite element analyses were carried out by using a commercially available finite element software code,
MIDAS/GTS. The analyses were carried out using three different sets of constitutive relationships for
different track layers: (i) Non-linear analysis- Different track layers were simulated using hyperbolic
Duncan Chang model, (ii) Straight analysis- Subgrade soil was simulated using elasto-plastic, Mohr-
Coulomb, total stress (undrained) relationship but ballast and subballast were simulated using effective
stress (drained), Mohr-Coulomb relationship and (iii) Coupled analysis- Subgrade soil was simulated
using a coupled pore water pressure stress, time-dependent formulation under an elasto-plastic, Mohr-
Coulomb constitutive relationship but ballast and subballast were simulated using effective stress
(drained), Mohr-Coulomb relationship.
The thesis deals with the current problem of Indian Railways, which bear huge economic losses due to
constant maintenance of railroad tracks on account of subgrade shear failures and mud pumping
problems on clayey subgrades. The work was fully industry oriented and relevant to the present day
needs of Indian railways to increase the transportation efficiency by running heavier, longer and faster
trains. The work embodied in my thesis was a part of a Department of Science and Technology (DST)
Project No: RP02804 entitled “Experimental Investigations and Analysis of Geosynthetics Reinforced
Railway Tracks Laid on Clayey Subgrade”.
