一、引言 峡东是长江三峡东段,即鄂西秭归往东至宜昌附近峡谷区的简称。研究区虽然以弱震活动为特征,但鉴于在工程上的重要位置,历来研究者甚多,因而为该区地震地质和地壳稳定性的研究积累了丰富资料。在前人工作基础上,根据多年来集体工作成果的综合分析,作者试就峡东地段所处的地震构造环境及其有关问题作一粗浅分析和讨论。
I. Introduction Gap East is the eastern part of the Three Gorges of the Yangtze River, that is, west of Hubei Province go back to Yichang Gorge area of the short name. Although the study area is characterized by weak earthquakes, there are still many researchers in view of its important position in engineering. Therefore, a great deal of information has been accumulated on the research on the seismic geology and crustal stability in this area. Based on the previous work, based on the comprehensive analysis of the collective work achievements over the years, the author tries to make a superficial analysis and discussion on the seismic tectonic environment and other related problems in the Xiaodong area.
