Numerical Analysis of the Carrying Capacity of a Piled Raft Foundation in Soft Clayey Soils

Piled raft foundations are a common type of foundation for high-rise buildings. Unlike shallow foundations, deep (piles) pass through weak or soft soil deposits and can reach stiff bedrock to support the weight structure. In this paper, performance medium embedment depth piled in is presented. A numerical model was developed parametric study conducted order simulate case such system investigate its clay. This investigated effect geometry stiffness ratio between pile material clay on soil. Additionally, failure mechanism under load examined. An analytical predict ultimate carrying capacity based observed mechanism. semi-empirical proposed determining Improvement Factor (IF) given soil, pile, geometric condition. Findings indicate that soils significantly affected by piles’ spacing. As S/D increases, decreases. However, when exceeds 10 (S/D> 10), piles have little no system. fails bearing at base also shear side group hyperbolic plans. Doi: 10.28991/CEJ-2022-08-04-01 Full Text: PDF
