Evaluation of Methods Based on CPTu Testing for Prediction of the Bearing Capacity of CFA Piles

Analysis of pile bearing capacity is an important task in the investigation soil-structure interaction. The paper dedicated to prediction methods for calculation based on cone penetration test (CPTu) results, namely UniCone method, Laboratoire Central des Ponts et Chaussées method (LCPC), and involved Eurocode 7—2. A set CFA piles was tested obtain reference capacity. ability determine investigated. In each evaluation criteria using statistical tools, were ranked their performance. results study indicate that most applicable given conditions. EC 7—2 showed largest variability we do not recommend its application without a deeper analysis. applicability any presented cannot be considered final or universal. It advisable use more modern updated which have been developed from larger database tests. development these should continue by expanding together with advanced rock environment testing procedures.
