上寺地表破裂带及其形成机制的初步认识

CHARACTERISTIC OF SURFACE RUPTURE ZONE AT SHANGSI AREA AND ITS FORMATION MECHANISM

摘要:

在详细描述破裂带几何形态、展布特征及力学性质的基础上,对上寺地表破裂带的形成机制进行了初步探讨.结果表明,上寺地表破裂带是1927年古浪8级地震破裂带的组成部分.

Abstract:

Geometric pattern, distribution features and mechanics nature of surface rupture zone at Shangsi area are described. The mechanism of formation of the surface rupture zone is studied. It is proved that the Shangsi rupture zone is engendered during the Gulang earthquake,and is part of the rupture zone of the 1927 Gulang M_S8 earthquake.
