Abstract: With the rapid development of China's transportation industry, bridge engineering also ushered in a largescale construction and development. In the construction, a variety of new technologies and new processes are constantly emerging, which greatly improves the quality of bridge construction. This paper takes the cantilever cast-in-place construction technology of prestressed concrete continuous bridge as an example, on the basis of comprehensive understanding of cantilever construction method, relying on a bridge project, expounds the construction technology points, in order to comprehensively improve the bridge construction quality.
