| Abstract: | In this study,the working mechanisms of wedged anchorage and traditional pre-stressed anchorage are analyzed based on synchronized hydraulic lifting devices.By investigating the engagement between steel strands and wedge teeth,the mathematical and simulation models are established to quantitatively assess the wedged tooth strength and decontaminant capacity.Accordingly,it is indicated from results that such properties as the hardness matching between wedge and steel strand,tooth shape and parameters,and geo... |
