摘要
2008 年5 月12 日14:28，中国四川省发生了8 级地震。地震中发生了大量的地址灾害，比如落石，边坡滑坡等。在直下型地震中该地震的规模可算是世界最大及地震，可以与1927 年的古浪地震，2001 年的印度西部地震及日本1981 年的农尾地震相匹敌。地震灾害集中分布于以震中为起点的东北方向的震源断层带。岐阜大学的所在地岐阜县是日本过去的农尾地震的受灾地，基于自他的教训活用于相互的复兴及灾害防治将无比重要的精神，岐阜大学先后两次对四川地震进行了现场调查。本报告，作为速报，对灾区的斜坡及地基灾害进行率直的报告，并对以地基灾害为中心的灾害情况进行简要的分析和评价。
ABSTRACT:
The Sichuan earthquake occurred on May 12, 14:28 (local time) in China.A great number of geological disasters such as rockfalls, slope failures and landslides took place during the earthquake. In this report, the result of a preliminary site investigation is briefly introduced. Several kinds of disasters near the epicenter are summarized. The effects of countermeasures against geological disaster such as slope net, shotcrete, slope anchor and reinforced soil wall are also discussed based on the filed observation. In particular, the prevention of second disaster is emphasized.
