摘要
郯庐断裂带作为一条现今仍在活动的巨型走滑断裂带,对沿线区域构造、地震活动、地裂缝灾害产生重要影响。基于文献调查和对比研究,总结郯庐断裂带中段沿线地裂缝的发育情况及空间分布规律,分析郯庐断裂带对沿线地裂缝的控制作用。研究表明,郯庐断裂带中段沿线地裂缝在地表具有北多南少、近密远疏、北强南弱、走向性明显等分布规律,其形成和显现受区域构造运动、断层蠕动、地震作用和人类活动、外动力作用等众多因素的影响。研究成果对郯庐断裂带中段沿线地裂缝灾害的防治具有一定指导意义。
As a giant strike-slip fault zone that is still active today,the Tan-Lu fault zone has an important impact on regional structure,seismic activity and ground fissure disasters along the fault.Based on literature survey and comparative study,the development and spatial distribution of ground fissures along the middle section of Tan-Lu fault zone are summarized,and the control effect of Tan-Lu fault zone on the ground fissures is analyzed.The research shows that the ground fissures along the middle section of Tan-Lu fault zone have the distribution rules of more in the north and less in the south,close to dense and far to sparse,strong in the north and weak in the south,and obvious strike.Its formation and appearance are affected by many factors such as regional tectonic movement,fault creep,earthquake,human activities and external geological effects.The research results have certain guiding significance for the prevention and control of ground fissure disasters along the middle section of Tan-Lu fault zone.
