Abstract

The article provides an analysis and comparison of the bearing capacity of barrett piles in difficult geological conditions at a construction site in Hanoi - Vietnam based on the results of analytical calculations using various methods. In particular, it contains calculation results according to Building Code of Russian Federation SP 24.13330.2011 "Pile foundations" [1], by numerical modeling of the pile operation under load using the PLAXIS 3D and MIDAS GTS NX software package, based on the results of field tests with piles (static load method). It is noted that the bearing capacity of bored piles and barret piles, according to the results of full-scale static tests with a limiting settlement of 40 mm, is in good agreement with the numerical solution (with the adopted soil model Hardening Soil (HS)) and with the calculation by the analytical method according to the strength characteristics of the soil base
