Assessment of the bearing capacity of piles in soil, determined by static and dynamic load tests

Abstract

The article presents the results of a comparison of partial values of the carrying capacity of piles obtained by static and dynamic tests. The tests were carried out for driven piles, cross-section 30x30 cm. The complex of investigations is represented by more than 150 pile soil tests carried out in accordance with the requirements regulated by GOST 5686. On the basis of the results we analyzed convergence of the compared test methods and statistical analysis of data. The results of the analysis have shown that all obtained private and average values of bearing capacity are acceptable and have a close relationship with each other. The research is of practical importance for further construction of the oil and gas complex. The revealed regularities will allow to make correction of dynamic express method results in relation to a static method, which is considered to be a reference one. A large number of obtained private values of bearing capacities provides statistical reliability of the obtained results.
