According to the drawing load characteristics of horizontal rectangular anchor plate in red clay foundation, the vertical drawing model test of horizontal rectangular anchor plate in saturated red clay foundation is carried out by using a self-made visual drawing model test system combined with digital photographic measurement technology. The results show that the sliding surface of soil around the anchor shows different shapes with the change of buried depth ratio, but the initial Angle does not change with the change of buried depth ratio. The load displacement curve generally has obvious peak characteristics, but with the increase of the buried depth ratio, the characteristics gradually weaken. When the buried depth ratio is the same, the smaller the length-width ratio is, the more obvious the three-dimensional bearing characteristics of the anchor plate and the peak characteristics of the curve are. The bearing capacity coefficient increases with the increase of buried depth ratio, but the law is different under different aspect ratio. The bearing capacity coefficient decreases with the increase of length-width ratio, and the change law is consistent under different buried depth ratio. Conclusion: For test red clay, the anchor plate can be classified as shallow buried type at least within the range of buried depth ratio 4, and deep buried type if the buried depth ratio is greater than 8. Under the same conditions, under the influence of cohesion and dilatancy, the tensile strength coefficient of anchor plate in red clay foundation is between loose sand foundation and dense sand foundation.
