The invention discloses an arch bridge main arch construction method and an assembly type arch bridge construction method. The arch bridge main arch method comprises the following steps: step a, dividing a main arch into a plurality of main arch split bodies with the same shapes in the width direction, sequentially dividing each main arch split body into a front section, a middle section and a rear section in a span direction, and enabling two dividing surfaces to be planes with the bending moment of 0 on the main arch; step b, prefabricating the front section, the middle section and the rearsection; and step c, after prefabrication is completed, splicing all the sections and hoisting the sections on a bridge abutment of the arch bridge. According to the invention, the main arch is divided into the main arch split bodies; the main arch split body is divided into the front section, the middle section and the rear section, so that all the parts can be prefabricated and are convenient totransport and hoist, water pumping and blocking do not need to be conducted on a river; the two dividing surfaces of the main arch are the surfaces, with the bending moment being 0, of the main archsplit body in the uniform load state, so that the load capacity of the main arch can be guaranteed, and the service life of the main arch is prolonged.
本发明公开一种拱桥主拱的建造方法及装配式拱桥的建造方法，包括以下步骤：a.沿宽度方向将所述主拱分为形状相同的若干主拱分体，沿跨度方向将主拱分体依次分割为前段、中段、后段三部分，且两分割面为主拱上弯矩为0的平面；b.对前段、中段、后段进行预制；c.预制完成后将各段进行拼接并吊装在拱桥的桥台上；本发明通过将主拱分为主拱分体，并将主拱分体分为前段、中段、后段，使得各部分可进行预制，并方便运输、吊装，无需对河流进行抽水、阻断，并且本发明中将主拱的两分割面为主拱分体受均匀载荷状态下弯矩为0的面，能够保证主拱的载荷能力，延长主拱寿命。
