The damage mechanism of water tower in Shaanxi Provence during Wenchuan Earthquake
Through the collection,collation and analysis of the data about damage of Water tower in Shaanxi Provence during 12 May 2008 Wenchuan Earthquake,the mechanism of long-period damage of the water tower is given.The analysis shows that,in Hanzhong basin,Ankang basin,and Weihe basin,serious damage should be caused by the long-period effect of basin of large earthquake in the far field.That magnitude of Wenchuan Earthquake is high,three basins are at the direction where the Wenchuan Earthquake wave propagated,and the epicentre is from 400 to 600km determines that the Wenchuan earthquake has the condition producing long-period effect in the three basins.In addition,the basins have very thick deposits,as well as possible basin edge effect may enhance long period damage.The damage of long-period of water tower results from the resonance between water tower and long-period ground motion.
