Statistical Evaluation of CPT and CPTu Based Methods for Prediction of Axial Bearing Capacity of Piles

摘要: Piles are structural members made of steel, concrete, or wood installed into the ground to transfer superstructure loads soil. Nowadays, many structures built on poor lands, and therefore piles have crucial roles in such structures. Performing in-situ tests as cone penetration (CPT) piezocone (CPTu) always been great importance designing piles. These a brilliant consistency with reality, result, outcome data can be used order achieve reliable pile models reduce uncertainty this regard. In paper, capability various CPT CPTu based methods developed from 1961 2016 has investigated using four statistical methods. Such adopted for direct prediction axial bearing capacity field data. For purpose, 61 sets prepared collected. The were utilized calculate (QE) through 25 different addition, measured capacities (QM) collected, recorded static load tests, respectively. Then, approaches applied assess accuracy these Finally, most accurate presented.
