The article presents the results of analytical analysis of the bearing capacity of a single baretta in hard geological conditions in the city of Hanoi and compares it with the field test results. The methods provided in the regulatory documents SP 24.13330.2011 “Pile Foundations” [ 1 ] have been adopted when determining the bearing capacity of piles and barrettes. As well as the results of field tests with piles (static load method) were used. A new method has been proposed which accounts the mutual arrangement of piles in the ground, their length, pitch, etc. Appendix E of the specified regulatory document provides this method. The investigation shown that the test bearing capacity of a single barrette with a limiting settlement of up to 40 mm is in a good agreement with the results of analytical analysis by proposed method, which accounts unloading on soft soils in deep pits.
