| 摘 要： | 本文根据多年野外考察资料,在论述1927年古浪大震形变带及发震断裂带特征基础上,分析了地震发生的地质构造背景,认为这次大震是塔儿庄—皇城断裂带和武威—天祝断裂带同时活动的产物,同时对两组断裂破裂方式进行了初步分析,提出了断块错动力学模型。

| Abstract: | In this paper,based on the data of virtual investigation,the author has discussed the characteristics of deformation band and earthquake frac-ture of Gulang earthquke in 1927 and analysed the geotectonical back-ground of this earthquake.The author helieves that the occurrence of Gulang earthquake in1927 Was the result that the fracture band of Tazhuang-Huangcheng andthat of Wuwei-Tianzhu were in activity at the sametime.And based no the analysis of their rupturing way,the mechanics model of fragmentation massif movement has been made. |
