古浪地震滑坡的分布规律和构造意义

Distribution and Tectonic Implications on the Gulang Seismic Landslide

１９２７年古浪地区发生了一次８级地震，地震时诱发了大量的滑坡和崩塌。本文根据野外调查和航片解译，分析了古浪地震滑坡的分布规律，探讨了古浪地震的地面破坏类型和滑坡滑动方向与区域构造应力场的关系。

In 1927, an earthquake occurred in the Gulang region, and a great number of landslides, slumps occurred at the same time. This paper analysed the Gulang seismic landslide distribution based on field investigations and interpretative result from air-photos, and researched ground rupture type of the Gulang earthquake and the relations between the tectonic stress field and the slip direction of the landslides in this region.
