Embodiment Construction
[0028] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] Such as Figure 1 ~ Figure 3 As shown, the composite steel plate girder bridge pier girder solid structure of the present invention includes an I-shaped steel girder and a beam arranged between the steel girders. The steel girder includes an upper flange plate 1-1, a web 1-2, Lower flange plate 1-3, transverse stiffener plate 1-4, longitudinal stiffener plate 1-5; beam includes upper flange plate 2-1, web plate 2-2, lower flange plate 2-3; passed value According to the analysis, the contact between the lower flange plate 1-3 of the main girder and the outer edge of the pier bears a relatively large local pressure. The lower flange plate 1-3 is equipped with longitudinal stiffening ribs 1-5; the inner sides of the main girder web 1-2 and the beam w...
