Cantilever irrigation method construction continuous beam and continuous rigid frame bridge geometrical parameter structure
The invention discloses a cantilever irrigation method construction continuous beam and continuous rigid frame bridge geometrical parameter structure. A continuous beam and continuous rigid frame bridge comprise a zero section, a mid-span cantilever section, a side-span cantilever section, a side-span straight line section and a closure section; the length A of the zero section is larger than 10 m and smaller than 12 m, and the larger the span of the bridge is, the larger the A is; the length D of the side-span straight line section is larger than 2 m and smaller than 3.5 m, and the larger the span of the bridge is, the larger the D is; the length B of the mid-span cantilever section is characterized in that the length of the section close to a main bridge pier ranges from 2.5 m to 4 m, and the lengths of the other sections range from 4 m to 5 m; the length C of the side-span cantilever section is basically the same as the B; the length E of the closure section ranges from 1.5 m to 2 m. The lengths of all sections of the bridge are reasonably defined, convenience is brought to construction, and the construction efficiency and the construction safety are improved.
