本文对位于中国陕西省西安市以南约 30 公里的太乙河东支流秦岭东岔河谷的翠华岩崩进行了调查。滑坡起源于沿地震活动断层系统的岩石构造结构。它的发生可能与公元前 780 年的一场地震有关，这场地震必定引发了山体滑坡。由于稳定的人类输入，筑坝的天池前的滑坡区成为了该地区原住民的定居区，在过去的 2780 年里，他们利用这种快速的地貌变化系统来满足他们的需要。如今，该湖被认为是饮用水、农业和水力发电厂的水库。更何况翠华岩崩沉积物已成为观光、度假的旅游胜地。 (C) 2002 年，爱思唯尔科学有限公司出版。
This paper deals with an investigation of Cui Hua rock avalanche, in the Qin Ling Mountains, in the Dong Cha valley, an eastern branch of Taiyi River, some 30 kin south of Xi'an, Province of Shaanxi, P. R. of China. The landslide originated on lithotectonic structures along seismic active fault Systems. Its occurrence could be correlated with an earthquake in 780 BC that must have triggered the landslide. Due to a stabilizing human input the landslide area in front of the dammed Tianchi Lake became an area of settlement for native people of this area, which used this rapidly geomorphologic changing system for their needs over the past 2780 years. Nowadays the lake is considered to be a reservoir for drinking water, agriculture and a hydropower plant. Even more the deposit of the Cui Hua rock avalanche has become a touristic place for sightseeing and vacation. (C) 2002 Published by Elsevier Science Ltd.
