山西省交城断裂带东马峪构造地裂缝的影响范围及风险管控研究

Study on influence range and risk control of Dongmayu structural ground fissure in Jiaocheng fault belt

文章基于地下断裂向浅部扩展形成地表裂缝的断层形成机制,通过分析交城断裂带东马峪构造地裂缝上下盘裂纹破裂形式,计算了其影响范围。结果表明,地裂缝两侧影响范围受交城断裂活动的影响有所不同,上盘影响范围较下盘大;划定了地裂缝的影响范围分区,提出各区的风险管控建议。

Based on mechanism of ground fissure fault formation by expanding up to shallow of Underground fault and analysis of fracturing style of the upper and lower plate of Dongmayu ground fissure in Jiaocheng fault belt calculation of influence range of the fissure is made.The influence range on either plates of the fissure is controlled by Jiaocheng fault activity but the influence range at the upper plate is bigger than that of the lower plate.Division of the influence range is made and risk management and control suggestions are put forward.
