Abstract

Abstract

Soft ground is one of common applicable conditions of transmission tower screw anchor foundation. In order to understand the uplift bearing capacity of screw anchor in soft soil, in-situ uplift loading tests of screw anchors with different diameters, depths and spacings of anchor plates were carried out. The load-displacement relationship curve and ultimate uplift bearing capacity of single anchor foundation were obtained, and the uplift resistance of screw anchor in mud soft soil was analyzed,as well as the effects of diameter, number, depth, and bearing layer properties of anchor plate on the uplift bearing capacity of screw anchor. The results showed that the relationship between load and displacement of screw anchors in soft ground had smaller plastic load and longer plastic deformation stage; the larger the diameter of anchor plate and the more anchor plates, the higher the bearing capacity; when the ratio of the distance between adjacent anchor plates to the diameter of anchor plate was larger than 2.0, the interaction of a screw anchor between the anchor plates could be neglected, and the effect of the anchor plate bearing layer on the uplift bearing capacity of the screw anchor was more obvious than that of the buried depth.
