| 摘 要： | 详细描述了 5个地裂缝区的展布特征 ,分析了临汾市的构造环境 ,并与地裂缝的力学性质和活动水平进行了对比 .结果表明 ,临汾市地裂缝灾害的成因不尽相同 ,新构造活动与地裂缝的形成和发展关系非常密切 ;NNE向的地裂缝是基底断裂右旋扭动作用的产物 ,龙祠地裂缝是基底断裂伸展作用的产物 ;构造活动是诱发和控制地裂缝形成和发展的第一大因子 .

| Abstract: | The distribution characters of five earth fissure zones in Linfen were studied. The tectonic environment was analyzed in detail and contrasted with the mechanics property and activity of earth fissures. The result shows that it is different in genesis for different earth fissures. The new tectonic activity is closely related to the earth fissures. The NNE direction earth fissures are the result of dextrogyrate action of floor faults while the Longci earth fissure is resulted from the extension action of floor. The tectonic activities are the most important factor inducing and controlling earth fissures. |
