Experimental Study of Model Combined Piled Raft Foundation in Cohesive Soil Under Eccentric and Inclined Load

The combined piled raft foundation is a unique foundation type that combines the advantages of shallow foundations, such as mat foundations and deep foundations, like pile foundations. When a raft alone is unable to bear the load effectively, piles are added primarily to enhance its resistance against failure. In cases where the raft's bearing capacity is adequate to support the total load with a reasonable safety margin, the addition of piles aims to minimize settlements to an acceptable level and increase bearing capacity of the combined system. This experimental study was conducted on CH type cohesive soil, and the objective is to investigate the behavior of a piled raft foundation under various eccentric and inclined loading condition. This study encompassed a model foundation test that examined different combinations of load eccentricity (e) equal to 0, 0.05B, 0.10B & 0.15B, where B represents a width of the raft and for load inclination angles (θ) equal to 0°, 30°, 45°, 60° and e/B = 0 specifically for a load inclination angle of 90° (lateral load), all relative to the concentric vertical axis. The research findings provide valuable insights and serve as a reference, demonstrating that as the load inclination angle increased from 0° to 60° relative to the concentric vertical direction, the initial yield load (IYL) and final yield load (FYL) are decreased to almost 50% of the load for the e equal to 0.15B and differential settlement increases extensively for the e equal to 0.15B for all the load inclination angles (θ) as compared to other eccentricities.
