Geotechnical Evaluation of Mini Concrete Pile Foundations for the Gölcük-5 Self-Consumption Solar Power Plant (SPP)

Viranşehir / Şanlıurfa

Designed Solution

  • Evaluation of 15 static plate load tests carried out by Geotech,
  • Determination of deformation moduli and coefficients of subgrade reaction in accordance with DIN 18134,
  • Back-analysis of a representative plate load test using PLAXIS 3D to calibrate the geotechnical model parameters of the uncontrolled fill,
  • Assessment of the deformation behavior of the mini concrete pile foundations supporting the solar panels under design loads using three-dimensional finite element analyses.
