Reliability Analysis of Static Pile Capacity for Concrete in Cohesive and Cohesionless Soils

Authors : J.O. Afolayan and D.A. Opeyemi

Abstract: This study examined the reliability assessment of the carrying capacities of piles based on static approach with special consideration to pre-cast concrete as pile type in cohesive and cohesionless soils. The concept of the First-Order Reliability Method (FORM) was adopted for the assessment. The results obtained show that the safety index for piling degenerates with increasing length of piles both in cohesive and cohesionless soils. However, the static pile capacity is grossly conservative in cohesive soils and while it is highly unsafe in cohesionless soils. In fact, the safety index ranges from about 2.5-0 when pile length is between 10 and 30 m. Beyond this range of pile length, piling operation appears to be practically a failure in cohesionless soils.
