摘要
2008 年5 月12 日14:28，中國四川省發(fā)生了8 級地震。地震中發(fā)生了大量的地址災(zāi)害，比如落石，邊坡滑坡等。在直下型地震中該地震的規(guī)模可算是世界最大及地震，可以與1927 年的古浪地震，2001 年的印度西部地震及日本1981 年的農(nóng)尾地震相匹敵。地震災(zāi)害集中分布于以震中為起點的東北方向的震源斷層帶。岐阜大學(xué)的所在地岐阜縣是日本過去的農(nóng)尾地震的受災(zāi)地，基于自他的教訓(xùn)活用于相互的復(fù)興及災(zāi)害防治將無比重要的精神，岐阜大學(xué)先后兩次對四川地震進(jìn)行了現(xiàn)場調(diào)查。本報告，作為速報，對災(zāi)區(qū)的斜坡及地基災(zāi)害進(jìn)行率直的報告，并對以地基災(zāi)害為中心的災(zāi)害情況進(jìn)行簡要的分析和評價。

 

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.
