摘要
根据物探、钻探、地貌等资料证明了王湖—北田断裂和郭家堡—南沟隐伏断裂的存在及其活动性 ,并从地裂缝的分布及其活动特征、地震、地下水、地貌、地形变等诸方面论证了榆次地裂缝是由于断裂活动间接所致 ,属于构造成因。同时地震活动、地下水超采加剧了地裂的发展。
According to the data of physical exploration,drilling,landforms etc.,we proved the existence of Wanghu Beitian fault and Guojiabu Nangou fault as well as their activity.Through discussion in distribution of faults and its activity feature,seismic distribution,underground water,landforms,crustal deformation etc.,it is confirmed that Yuci ground fissure was cause by fault activities,which is one kind of tectonic cause.Seismicity and overextraction of underground water intensified the development of the fissure.
