Full-span precasting for light-rail transit and high-speed railway bridges

摘要

>Full-span precasting is a consolidated construction method for large-scale light-rail transit and highspeed railway prestressed concrete bridges. Full-span precasting offers rapid construction; repetitive,? highquality casting; and year-round erection. The paper examines the organization of full-span precasting facilities for light-rail transit and high-speed railway beams as well as the loading, kinematics,??? support and launch systems, performance, productivity, and structure-equipment interaction of the equipment used for transport and placement of full-span precast concrete beams.
