Calculation of bridge piled foundations

Calculation of piled foundations and their beds is carried out according to two groups of limit states. The design of the piled foundation is selected based on the specific conditions of the building site, which are characterized by engineering survey data, constructional aspects of the designed facilities, and design loads acting on the foundation. The paper provides recommendations on calculating the bearing capacity of piled foundation of bridges supported on non-rocky soil, as well as embedded in rocky soil using the values of the reliability coefficient, provided that it is determined by the results of static load tests. Consideration of these recommendations will make it possible to exclude the adoption of excessively complicated solutions for foundations and construction operations, as well as unjustified rise in the cost of construction.
