Prediction of pile bearing capacity has been considered an unsolved problem for years. This study presents a practical solution the preparation and maximization capacity, considering effects time after end driving. The prediction phase proposes intelligent equation using genetic programming (GP) model. Thus, geometry, soil properties, initial driving were predictors to predict capacity. develop...

Concrete piles that were poorly constructed or analyzed in their soil analyses may have structural geotechnical defects. To examine such defects, an experimental study was conducted to investigate how a defective reinforced concrete pile behaved. These installed and subjected compression axial load the sand had relative densities of 30%,60%, 80%. The tests performed using four model piles: one ...

Socket connection need a groove reserved in the cap to accommodate bridge pier, which greatly weaken vertical bearing capacity of cap. The conventional treatment measure is increase thickness cap, and corresponding cost will increase. measures enhance socket caps without increasing were discussed this paper, including rough interface at bottom additional hanging bars, high-strength grouting mat...

This paper mainly uses the method of model test to study ultimate uplift bearing characteristics a single pile with different length-to-diameter ratios, from distribution laws capacity pile, axial force and side friction perform analysis. The is made PVC pipe, resistance strain gauges are attached both sides pipe. value pipe under load conditions measured obtain working behavior during process ...

This article discusses the connection of a steel sheet pile to an I-beam by welding increase horizontal load-bearing capacity. The is checked during experimental study for axial tension. Deformations at reference and maximum loads, as well stresses in weld metal metal, are recorded. During tests, bearing capacity welded joints was confirmed, data on plastic deformations walls under various load...

In this paper, a numerical investigation of the effects grout parameters on load response concrete pile-grout systems in soft clay is presented. The study examines influence diameter and depth bearing capacity pile under vertical lateral loads. research findings indicate that grouting can enhance single system by up to 27% loads 51% loads, depending used. This due grout's ability fill voids soi...
