The purpose of this study is to assess the bearing capacity of drilling piles (BNS) of a continuous cross section with a diameter of 600 mm with the walls of wells fixed with inventory recoverable casing pipes at the construction site of the I.K. Aivazovsky International Airport in Simferopol. Static field tests of two BNS were carried out in accordance with the working draft and the requirements of the current regulatory documentation, and an analysis of the results was performed. Based on the conducted experimental studies, it was concluded that it is advisable to take into account the normative values of precipitation when determining the bearing capacity of piles on the ground. The results of field tests were compared with the calculated values determined in accordance with the recommendations of SP 24.13330.2011. It is noted that the load corresponding to the reference value should be taken as the criterion of the actual bearing capacity. The subject of the study: BNS of a solid section with a diameter of 600 mm with the walls of wells fixed with inventory recoverable casing pipes at the construction site of the I.K.Aivazovsky International Airport in Simferopol. Materials and methods: engineering and geological conditions of the construction site, design documentation for the foundation structures of the facility, the method of field testing of soils with piles has been implemented. Results: The measurement parameters of controlled pressure loads and displacements - sediment of the BNS are presented in tabular form and graphs using Excel software. Conclusions: The conducted field tests confirm the value of the calculated permissible load on the BNS, adopted at the design stage, which justifies the reliability and effectiveness of the constructive solution embedded in the project.
