摘要：
Based on the field investigation for secondary geological hazards induced by 5.12 Wenchuan Earthquake, the types of geological disasters during or after earthquake are analyzed in this paper. The main secondary geological hazards are rock fall and collapse, landslide, debris flow, dammed lake, sand liquefaction and so on. The development and distribution rules of secondary geo-hazards, with a long-term sustainability and a formation of hazard chains, are of relation with earthquake fault zone, and consistent with seismic intensity. The buildings located in secondary geo-hazards areas with a high risk are damaged severely, thus the site selection for post-earthquake reconstruction and related geotechnical engineering issue are discussed, which are useful in reconstruction of Wenchuan earthquake area.
