| 摘 要： | 汶川地震在甘肃南部造成了极为严重的滑塌灾害。本文在武都区附近地震滑塌灾害统计研究的基础上,阐述了其主要类型和发育特征;论述了甘肃地震滑塌灾害的展布主要受地形、岩性、地震烈度、人类工程活动和植被发育程度等因素影响,在空间上分布很不均匀。地震烈度高的陇南灾区地震滑塌密度相对较大;节理发育的厚层(块状)岩层滑塌较为突出;黄土滑塌较为突出。进而提出了山区地震滑塌灾害减轻的注意事项以及甘肃省不同区域滑塌灾害减轻对策。

| Abstract: | Wenchuan earthquake caused severe landslides and collapse disasters in southern Gansu province.The main types and characteristics of the disaster are expounded based on the statistical analysis on the earthquake disasters after Wenchuan earthquake in Wudu area.The earthquake slide-collapse disasters in Gansu were mainly affected by terrain,lithological characters,seismic intensity,human engineering activity,vegetation covering ratio and other factors.The distribution is not uniform.The density of earthquake... |
