摘要
汶川地震后两年,成都平原多个县区出现地面塌陷。就地质环境而言,成都平原不具备自然地下空洞引发大型地面塌陷的地质条件。现有地面塌陷均为人为地下空洞在自然或人为因素下引发。汶川地震缩短了产生地面塌陷的时间,致使成都平原在地震后两年内较高频率发生小规模地面塌陷。
Ground collapses occurred in Chengdu Plain two years after Wenehuan Earthquake. In terms of geo-environment, the plain doesn＇t have the geological conditions for underground caves. All the collapses there have resulted from man-made ca- ves, started by either natural or man-made factors. The earthquake shortened the time of occurring and resulted in frequent small-scale collapse occurrences within two years after the earthquake.
