摘要
本文着重介绍5.12地震后四川省巴中市巴州区崩塌地质灾害特征,分析它们发生和发展的地质环境背景,重点分析了崩塌类型与岩体结构的关系及崩塌发生的一些基本规律,结合具体实例,提出了汶川地震触发崩塌成因机制的分类体系,概括和总结了五种主要崩塌类型的基本特征及地质模式。
This paper introduces the distribution and development characteristics of the landslides in Bazhou District,Bazhong city of Sichuan province after 5.12 earthquakes. The geological environment background connecting to their occurrence and development are analyzed. Mainly attention is put on the relationship between landslides and rock structure,also the basic rule of landslides development. With special examples,we proposed the classification system of landslides formation mechanism that earthquake triggered. Finally,we summarized five main types of landslides and generalized their basic characteristics and geological models.
