Abstract

A shallow-foundation V-H-M space charge measurement experiment device comprises a plurality of crossbeams, a plurality of side beams, four longitudinal beams and a support frame composed of a plurality of diagonal braces. A soil groove for experiment is arranged on the lower portion of the support frame, a loading device used for adjusting a bucket-shaped foundation model in position is arranged on the upper portion, corresponding to the soil groove, in the support frame, and the loading device comprises a lateral loading movement mechanism used for adjusting lateral displacement of the bucket-shaped foundation model, a vertical loading movement mechanism located under the lateral loading movement mechanism and used for adjusting vertical displacement of the bucket-shaped foundation model and a bending moment oriented loading movement mechanism arranged on the vertical loading movement mechanism and used for adjusting angles of the bucket-shaped foundation model. Various loading combinations borne by wind power foundation can be accurately simulated, soil resistance and foundation deformation during the bearing process of the foundation can be effectively measured, and considerable accuracy and reliability are achieved; safe running of a fan during designed life service can be guaranteed.

Description

technical field

[0001] The present invention relates to a test device. In particular, it relates to a shallow foundation V-H-M space loading measurement experimental device. Background technique

[0002] As mankind enters the 21st century, the energy crisis is becoming increasingly prominent. As a renewable clean energy, wind energy has become a new direction to alleviate the global energy tension. However, as an important part of wind power generators—the wind power foundation has the characteristics of high construction cost and difficulty in construction and installation. Moreover, compared with the traditional structure foundation, it not only has to bear sufficient vertical load, but also bears large bending moment and large horizontal force. Under working conditions, the fan is not only subjected to static load, but also three-dimensional dynamic action. To sum up, due to the complexity and uncertainty of the mechanical characteristics of the wind power foundation,...
