Variable cross-section continuous beam bridge structure suitable for incremental launching construction and construction method
The invention relates to a variable cross-section continuous beam bridge structure suitable for incremental launching construction and a construction method. A steel web adopts variable cross-section beam height in the bridge direction, a bridge deck is a concrete bridge deck or a combined bridge deck or an orthotropic steel bridge deck, and the bridge deck is composed of two or three of the concrete bridge deck, the combined bridge deck or the orthotropic steel bridge deck in the bridge direction; the variable-cross-section steel structure continuous beam is a variable-height beam section at a middle fulcrum, other beam sections are equal-height beam sections, the length of the equal-height beam sections is larger than that of the adjacent variable-height beam sections, steel webs are divided into equal-height webs and variable-height webs in the bridge direction, and the variable-height webs are composed of upper equal-height web plates and lower special-shaped web plates which are sequentially connected from top to bottom. The bottom of the variable-height beam section is fixedly connected with a cover beam at the upper end of the pier; according to the structure, incremental launching construction of the variable-cross-section steel structure continuous beam bridge is achieved, partial limitation of incremental launching construction on the geometric shape of the bridge structure is broken through, the beam end is periodically constructed on a fixed site, and the construction quality and the construction progress are guaranteed.
本发明涉及一种适于顶推施工的变截面连续梁桥结构及施工方法，钢腹板顺桥向采用变截面梁高，桥面板为混凝土桥面板或组合桥面板或正交异性钢桥面板以及在顺桥向为上述三者的两种或三种组成；变截面钢结构连续梁在中支点处为变高梁段，其余梁段为等高梁段，等高梁段长度大于相邻变高梁段，钢腹板顺桥向分为等高腹板和变高腹板，变高腹板由上至下依次连接的上部等高腹板块和下部异型腹板块组成；变高梁段的底部与桥墩上端的盖梁连接固定；本结构实现变截面钢结构连续梁桥的顶推施工，突破顶推施工对桥梁结构的几何外形的部分限制，使梁端在固定场地上周期性施工，施工质量以及施工进度得以保证。
