CEMENT FLYASH, GRAVEL (CFG) pile is a useful method for increasing soft soil ground bearing capacity. Nowadays ground improvement is a significant prerequisite in current industry development for land recovery is ending progressively. Present study laboratory tests were conducted on CFG pile with 40, 60 and 90 mm diameter and length to diameter 3 and 4. A Lateral load was applied to investigate the ultimate bearing capacity behavior of the CFG pile. The main objective of this experimental investigation was to study the performance of a single CFG pile under lateral load in silty clay. An experimental result shows that lateral load-carrying capacity was increased by increasing the diameter of the pile. However, bending or ultimate lateral carrying capacities were remained less impact with infusing the higher L/D ratio of CFG pile.
