Design Scenarios for The Foundation of 85 m Height 400 Tons 2MW Wind Power Plant Aqmola Region

The problems in the design of foundations of wind power plants are presented. The purpose of the article is to develop experimental and theoretical recommendations for the calculation and design of foundations of wind power plants. A complex of theoretical, analytical, and numerical modeling of the foundations were used: analysis of natural-climatic and socio-economic zones of Aqmola region; collection of loads on the foundation of wind power plants using SCAD software and estimation of bearing capacity of foundation and soil-base. In total 3 design scenarios were adopted: slab, driven pile and bored pile foundations. The results revealed that the highest bearing capacity is in bored pile foundation with the value of 570 kN (960 kPa working load capacity), which is slab (580 kPa) and driven (470 kN, 770 kPa working load capacity) pile foundation. In terms of materials resources the most efficient appeared to be the scenario of driven pile foundation.
