Factors Influencing Dynamic Response of Geocell Reinforced Soil Beds
This study describes the influence of various factors on the dynamic response of geocell reinforced beds subjected to machine induced vibration. A series of field vibration tests were conducted on two different foundation beds, namely, unreinforced and geocell reinforced. The studied factors include depth of placement of geocell, the width of geocell, and infill materials. Four different geo-materials were used to quantify the effect of infill material on geocell performance. From the results, the optimum width and depth of placement of the geocells for the maximum improvement in the performance were observed as 5B and 0.1B respectively. At the optimum width and depth of placement, a 49% reduction in peak particle velocity (PPV) of the foundation bed was observed. In addition, the peak displacement amplitude of vibration was decreased with the increase in the angle of shearing resistance (ϕ) of infill material.
