In the present paper, the dynamic response of the confined geomaterial subjected to vibratory load has been investigated using a numerical program supported by experimental findings. An accelerometer has been used to report the acceleration, velocity, and displacement of confined geomaterial fill along the depth at varied frequencies of vibratory load. Further, the experimental findings were used in the numerical program to obtain the shear modulus and damping of confined geomaterial. The stress–strain response shows compounded effects with an increase in frequency and modulus of elasticity. It has been observed that displacement is amplified by 10–90% for a frequency range of 5–75 Hz. The shear stress–strain results showed that the shear modulus is magnified by 50% for varied input parameters considered in the study. The damping of the confined geomaterial has been found to be 0.5–5% for varied unit weight inputs (16–22 kN/m3). The results are compared within the outputs obtained by numerical simulation and experimental analysis for estimating the dynamic properties of the confined geomaterial subjected to vibratory load. The outcomes of the present study can effectively be adopted by engineers and partitioners for estimating the dynamic properties of the confined geomaterial in construction practices.
