| Abstract: | A Study on the structure of girderless trifurcation is carried out by means of classical mathematics, 3 D finite element method and model test. The results show that the stell lining reinforced concrete girderless trifurcation, comparing with the exposed steel girderless trifurcation, has the advantages of less plate thickness, easy to construct, higher safety and lower cost. |
