Abstract: Combined with the example on the cradle test of the (40+64+40) meter continuous beam of Lufeng double track big bridge in Guangtong�Kunming Railway Engineering in Yunnan, the result of preload test was analyzed and compared with structure theory. The results showed that by the use of normal prestressed reinforcement of zero block to preload the cradle by jack is simple, safe and highly applicable.
Key words: bridge engineering;continuous beam; cantilever construction; cradle test
