Numerical Analysis of Piles Group Surrounded by Grouting Under Seismic Load
The present paper aims to study the behavior of piles group surrounded by grout material under the effect of seismic loads. In this study, El Centro earthquake data were used as input time acceleration history with maximum peak ground acceleration (PGA) of 0.31g. Several cases were analyzed numerically to evaluate the piles group behavior under the effect of an earthquake. The first case included the impact of seismic loads on the piles group behavior without grouting; the results showed that the maximum seismic settlement was about 45 mm. The second case included improving the soil surrounding the piles with grout material at different depths and diameters. The results showed a decrease in the maximum seismic settlement value when the piles surrounded by grouting of the radius (0.5, 1, and 1.5 m) and extended to a depth of 2 and 4 m. The maximum value of settlement of the pile group was 28, 24, and 20 mm when surrounded with grouting of radius 0.5, 1, and 1.5 m, respectively, and extended to a depth of 2 m. The maximum amount of seismic settlement decreased to 25, 21, and 19 mm for grouting radius of 0.5, 1, and 1.5 m, respectively, when the grouting depth increased to 4 m.
