| Abstract: | In this paper, plane model and crossbeam model of an oblique concrete self-anchored suspension bridge are built to study the stress characteristics and control method in constructing phase. The results show that the characteristics of oblique bridge are similar with the normal bridge. The construction accuracy is weIl controlled and can meet the design requirements based on parameters modification, cable tension control and frequency test of suspension rod during construction process. |
