Model experiment on framed-tube embedded foundation for wind turbine
摘要
Abstract
A new framed-tube embedded foundation for the wind turbine is proposed, based on the mechanical properties of the traditional gravity foundation and the pile foundation, By the comparison and the analysis of two different sizes of the foundation model, it showed that bearing capacity of framed-tube embedded foundation was derived from the interaction between the foundation soil and the foundation. The failure mode and bearing capacity depended on the depth and bottom diameter of the foundation. The buried depth of the foundation increased with the decrese of the stress on the tube, and the failure mode was mainly partiac failure. The change of diameter could cause overthrow failure of the foundation. And the influence of the buried depth was more significant.关键词
