陕甘宁青地震形度带初步研究

PRELIMINARY RESEARCH ON EARTHQUAKE DEFORMATION BAND IN SHAANXI, GANSU, NINGXIA AND QINGHAI

摘要:

直到目前为止,国内外对地震形变带的认识还很不统一。本文根据大量的实际考察资料,阐明了研究地震形变带的重要意义。对其种类、名称等给予了特定的含义,对其特征作了较详细的阐述,分析了它的力学机理,论述了它与发震断裂的关系及其所反映的现代构造运动特点,进而初步总结了西北发生强震的主要地质标志,为预测未来强震提供了地质依据。

Abstract:

So far, the study on earthquake deformation band has not reached an identical view both at home and abroad. This paper, on the basis of enough data from practice and investigation, befines the kinds and names of deformation band, elucidating its properties in detail, analysing its mechanism of mechanics and expounding the relation between seismogenic fracture and deformation band, and the features of modern tectonic movement reflected by deformation band. Furthermore, in order to forecast the approaching strong earthquakes, the major geological signs are preliminarily summed up for strong earthquakes in the northwestern part of China.
