Main arch and stiff framework-concrete filled steel tube arch bridge
The invention relates to a main arch and a stiff framework-concrete filled steel tube arch bridge. The main arch comprises four main pipes, a plurality of in-arch transverse braces and a plurality of web braces, two of the main pipes are located on an upper chord, the other two main pipes are located on a lower chord, the four main pipes are connected through the in-arch transverse braces and the web braces to form a framework, and the four main pipes are filled with concrete; the main arch longitudinally comprises first main arch sections located at the two ends of the main arch and a second main arch section located in the longitudinal middle of the main arch, a framework of each first main arch section is wrapped with reinforced concrete to form a box-type structure, and each box-type structure comprises a top plate, a bottom plate and webs on the two sides. The framework of the first main arch section at the two longitudinal ends of the main arch is wrapped with reinforced concrete to form a box type structure, so that the bearing capacity of the first main arch section is enhanced, the stress problem that the axial force of the main arch of the arch foot section is large is effectively solved, the purpose of reducing the size of the main pipe is achieved, the weight of the arch rib section is lighter, the installation system is more economical, and the installation process is safer.
本发明涉及一种主拱及劲性骨架‑钢管混凝土拱桥。主拱，包括四根主管、若干拱内横联和若干腹联，其中两根所述主管位于上弦，另外两根所述主管位于下弦，四根所述主管通过所述拱内横联和所述腹联连接形成骨架，四根所述主管内均填充有混凝土，主拱纵向包括位于其两端的第一主拱段和位于其纵向中部的第二主拱段，所述第一主拱段的骨架外包有钢筋混凝土形成箱式结构，所述箱式结构包括顶板、底板和两侧的腹板。主拱纵向两端的第一主拱段的骨架外包有钢筋混凝土形成箱式结构，使得第一主拱段的承载能力被加强，有效解决拱脚段主拱轴力大的受力难题，达到可减小主管尺寸的目的，使得拱肋节段重量更轻，安装系统更经济，安装过程更安全。
