摘要
由于特殊的地形地貌和地质结构特征,5.12地震使陇南市武都区地质环境条件又一次恶化,主要表现为地层破碎、坡体稳定性差等.通过利用模糊综合评判法,对地震前后地质环境条件进行分析对比,确定了震前与震后地质环境改变的程度.
Due to the special geographical and topographical features in Wudu District,Longnan City,the envirohmental conditions were further deteriorated. A fuzzy comprehensive evaluation method is used here to make a contrast between pre-earthqucke and post-eartquake so as to confirm the extent of changes in the geological environment.
