An algorithm for the ultimate pull-out force of horizontal anchor plates

anchor plates;  Characteristic lines;  Uplift;  logarithmic helix;  No cohesive soil

Aiming at the research status of the calculation method of the ultimate bearing capacity of horizontal anchor plates, considering the failure surface of the logarithmic helix and combining the characteristic line theory, a new calculation method for the ultimate pull-up force of shallow buried strip plate is proposed and a program is compiled. In this method, the traditional limit equilibrium method and the Soxhlet slip line method are coupled, and in order to avoid the intersection of the center region and the slip line field, the calculation mode of differential from the failure to the bottom plate is adopted. For non-cohesive soils, the results obtained by comparing with the experimental data of predecessors and the results obtained by Meyerhof and Adams theory show that the proposed method is correct and feasible.
