Substantial precast panels of building structures were damaged by the Wechuan earthquake, while research in allusion to cracking precast panels on the reinforcement with CFRP is not sufficient, through the secondary load bearing experiment of 12 prestressed concrete hollow slabs, effects of the stickup methods and stickup amount on the reinforcement of prestressed concrete hollow slabs were studied. According to the test result, change of ultimate bearing capacity of specimens, failure mode, load displacement curve were systematically analyzed , and it indicated that the bearing capacity of prestressed concrete hollow slab reinforced with CFRP with damage of various degrees was increased by 10% to 85%, while for minor damage, moderate damage, severe damage of the prestressed concrete hollow slab, the CFRP reinforcement methods of 100mm wide single-layer double-width, 75mm wide single-layer triple-width, 75mm single-layer fourfold-width should be respectively adopted.
