“…The data acquired by the system were more reliable and accurate compared to the other manual methods, for example, the theodolite technique. More details of the field-based investigation can be obtained from the previous works [36,37]. The data presented in Tables 1 and 2 above have been obtained by collecting undisturbed samples from the site from selected locations and carrying out laboratory tests following the procedures standardized by American Society for Testing of Materials (ASTM).…”

Foundations supporting infrastructure built on soft and compressible marine soil are unlikely to sustain due to possibility of undrained shear failure or excessive settlement of the supporting soil. This necessitates the importance of implementing an adequate ground improvement strategy. Among different techniques, soft soil reinforcing by the installation of stone columns is one of the most successful methods in terms of long-term stability of foundations. To investigate the load-settlement characteristics of such reinforced soil, a group of closely spaced stone columns was constructed at a location along the eastern coast of Australia. The site geology revealed thick layers of soft, compressible marine clay deposit. These stone columns were loaded by constructing earthen embankment and the resulting load-settlement characteristics were measured by an array of sensors. A two-dimensional plane strain analysis was performed using finite element modeling simulations. Comparison of numerical results with the field data demonstrated accuracy of the numerical model. Additional studies were carried out to investigate the efficiency of the model. This paper integrates the new findings from the full-scale field study and advanced numerical simulations while drawing pertinent conclusions.

Structures founded on soft ground are likely to be exposed to disastrous consequences due to possible undrained failure or excessive settlement unless proper ground improvement is undertaken. Soft soil improvement by granular reinforcement has numerous benefits in terms of strength and stiffness as well as accelerated consolidation. Foundation soil supporting transport infrastructure are in addition subjected to cyclic loading initiated by traffic movement. This paper presents the load-transfer and consolidation characteristics relevant to stone column reinforced soft ground supporting transport infrastructure.
