摘要

地面破坏效应强烈和地震地质灾害严重是汶川MS8.0地震震害效应的显著特点。地震地质灾害的分布与地震断层的分布密切相关,同时还受自然地理、地层岩性、地质构造和人类活动的影响和控制。论文结合北川县场地条件的分析,对汶川MS8.0地震中北川县地震地质灾害的发育特征、形成条件及诱发因素进行了系统总结。地震地质灾害分布与地震断层的关系表明地震对次生地质灾害起到了主要的控制与触发作用。
The strong effect of ground damage and the serious earthquake-induced geological disasters are the notable features of MS8.0 Wenchuan earthquake.The distribution of earthquake-induced geological disasters in the earthquake is closely related to the distribution of earthquake fault,at the same time,it’s also influenced and controlled by the physical geography,lithology,geological structure and human activities.The paper systematically generalizes the development characteristics,formation conditions and inducing factors of geological disasters induced by MS8.0 Wenchuan earthquake combining with analysis of site conditions in Beichuan County.The relations between earthquake-induced geological disasters and the earthquake fault indicate that earthquake plays an important role in controlling and inducing geological disasters.
