Ground gap

English to Russian Tech/Engineering Energy / Power Generation WIND TURBINES
FOUNDATION DESIGN FOR WIND TURBINES
Ground gap
No ground gap may occur under the quasi-permanent load combinations.
The rest of the unfactored load cases are permitted to cause ground gap only up to the centre of gravity of the bottom area of the foundation.

Foundation Design

Like the tower, the WTGS foundation design has its idiosyncrasies. RP2011 Section 8.6.1.5 describes “ground gap” limitations that amount to additional overturning stability requirements. One ground gap criterion requires that under IEC DLCs such as normal power production, no ground gap (i.e., zero bearing pressure) shall occur at the foundation-soil contact. Stated differently, this means that the contact stresses under the entire foundation footprint must remain in compression. Another ground gap criterion states that under service extreme loads, the ground gap shall not extend beyond the center of gravity of the foundation bottom area.
