Numerical modeling and natural research of the influence of piling filling on the existing base of the functioning oil and gas complex

   The article presents the results of numerical modeling and vibration monitoring on the study of the influence of the vibration effect of pile driving on the existing foundations of a functioning oil and gas complex located in Tengiz.

   The aim of the work was to determine the smallest allowable distance of the pile driving device that excludes vibration impact on the foundation and ensures safe operation of the plant.

   The article presents the results of vibration impact of pile driving at different distances from the basement, taking into account natural vibrations and technological processes, massiveness of the foundation, etc., the results of the excitation of the soil mass at various distances from the source of vibration exposure (driving), as well as the results of numerical simulation of the above described practical research. For the forecast of the minimum allowable distance, numerical simulation was used in the Plxis 2D software package.
