| Abstract: | Rigid-framed arch bridge is a new development based on truss arch structure and inclined leg rigid frame and so on. It is a statically indeterminate structure with thrusting force, featured with fewer component, small self weight, favourable wholeness, high rigidity, expedient construction, more advanced economic index and heautiful model and so on. Combined with extension project of Beijiang Bridge in Qingyuan, construction technics of rigid-framed arch bridge are briefly introduced. |
