Numerical Simulation of Compaction Load on Stress-Deformation Behavior of Soil Geosynthetic Composite Mass
Fill compaction in the construction of soil geosynthetic composite (SGC) walls is typically carried out by operating a compactor. Due to the multiple passes of a compactor, the compaction-induced stress (CIS) at any given section can be evaluated by considering the compaction load applied directly above the section under consideration. The compaction load can be modeled as a distribution load on top of each soil layer (Type I), or as a distribution load at the top and bottom of each layer (Type II). This paper aimed to evaluate and compare the effect of the above two compaction simulation methods on the stress and deformation behavior of a full-scale instrumented SGC mass, which is under the working stress condition. Results are evaluated in the form of compaction-induced stresses, stress and strain developed in the reinforcements, and volumetric strain of the SGC mass.
