Design and Construction of the Bridges on Guangzhou Metro Line 4

Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of bridges on urban rail transit are explored. At the same time, due to the first time used on a large scale in mainland of China, the short-line match method technology and the principles of the coordinate transformation are briefly introduced, and the formulas of spatial dimensional coordinate transformation for geometric shape control and calculating the translation amounts of precasting by the short-line method are deduced. In addition, some of the methods for the geometric shape control of the precasting by the short-line method and cantilever assembly of the segments are also briefly discussed.
