| Abstract: | Based on the analysis of optimized index of suspended wagon by cantilever casting from many prestressed concrete bridges, the triangle suspended wagon is adopted in the design of Hanjiadian 1# bridge. The force transmitting principle of kinds of components of the suspended wagon is studied and three-dimensional space finite element model is set up to give specific analysis of the loaded and distortion situation of suspended wagon during the construction and traveling. The calculated result shows that the design is in agreement with the construction. |
