Research conclusions:Combined with the special design principle of the earthquake relics and the principles of the minimum intervention，authenticity，reversibility and recognition of the preservation of cultural relics，and based on the analysis of the main structural style and the damage characteristics of the Wenchuan and Yushu earthquake relics，the intension of the anti － seismic reinforcement of the earthquake relics is presented in this paper． Namely，when the reinforcement is conducted for the relics，the reinforcement for the collapse － resistant capacity should be given the first place to the whole structure while the reinforcement of the member of the damaged structure should be given the second place． Also the corresponding reinforcing method is pointed out in this paper．
