| Abstract: | According to scientific investigation of the seismogenic structure,housing and the lifeline engineering damages and the secondary geological disasters induced by the Minxian-Zhangxian MS6.6 earthquake on July 22,2013,that the characteristics of seismogenic structure and seismic intensity distribution,damage characteristics and failure mechanism of houses in different intensity zones are introduced.Moreover,a thorough analysis of typical loess landslides are carried out,the damage characteristics of fault effects,amplification effects of mountain and slope effects are summarized as well.Based on the in-depth investigation of seismogenic structure,site conditions of the quake-hit areas,different houses damages and secondary geological disasters,some lessons have been proposed for reconstruction of the quake and seismic fortification in the future. |
