Abstract
Introduction. Last decades, piles foundations become more popular because of increasing height of buildings. It is necessary to determinate bearing capacity of pile while designing to reach the most efficient way for spending material and technical resources. The safest results can be received from static load tests, that’s why big developer companies in Arkhangelsk-city included this method for all buildings with nine or more floors. Unfortunately, there are a lot of tests that ended when the needed load is reached with small settlement, and the actual value of pile resistance can’t be found.
Materials and methods. In this paper, the analyzed results of static load test for 15 piles are presented. All of them were driven into marine clayey soils in solid or semi-solid state with a porosity coefficient of 0.49–0.61, an internal friction angle of 23–27°, a specific adhesion of 40–75 kPa and a deformation modulus of 25–32 MPa, layers above were close to each other on all construction sites. Processing the results were made by F.K. Chin method.
Results. We reached the ultimate load for every pile, also the proposals to estimate the bearing capacity of piles which didn’t reach the ultimate settlement were made.
Conclusions. Finally, it was determined, that the ultimate load can be evaluated if only loaded it within the range of elastic deformation and after that range you can predict the way of chart with empirical relation for reduce the test time. The relation between ultimate loads and actual loads in the buildings was found for two groups of piles. Also, was made the conclusion about the excessive length of piles.
