| Abstract: | Double-way curved sphere surfaced shake reduction-isolation bearing was adopted in the approach-span design of Xishan Tunnel project in Urumqi development zone. The finite element analysis shows that it can effectively reduce Horizon-load on the substructure of the bridge under earthquake and can achieve obvious economic benefits and social efficiency in the premise of no large cost increase. |
