拱桥受荷后,拱上构造和主拱圈是作为一个整体共同负荷的,因而明显地提高了结构的负荷能力。这种整体作用的大小和拱上构造的布局有着直接的关系,恰当的布局能改善结构各部位的受力状况,从而提高整个结构的负荷能力。 我国目前修建的石砌、混凝土及钢筋混凝土拱桥,仍广泛采用拱式拱上构造(腹拱)。本

After the arch bridge is loaded, the arch structure and the main arch ring are jointly loaded as a whole, thereby significantly increasing the load capacity of the structure. The size of this overall effect is directly related to the layout of the arches, and the proper layout can improve the stress conditions of various parts of the structure, thereby enhancing the load capacity of the entire structure. At present, China’s stone, concrete and reinforced concrete arch bridge is still widely used arched arch structure (abdominal arch). this
