| 摘 要： | 通过野外地质调查的方法,对2007年1月陕西省泾阳县龙泉乡新出现的地裂缝进行了初步勘察。地裂缝主要沿清惠渠西干渠的两岸断续分布,上下两盘错距约5 cm,且都倾向于水渠一侧。结合该区地质地貌特征和地震前兆观测手段资料变化,对该次地裂缝的展布、性质、活动特征及地裂缝快速发展时期该区周围环境的变化情况进行了分析,表明由于长期干旱,清惠渠的西干渠在输水过程中渗漏,从而引起黄土自重湿陷,造成此次局部地质灾害。此地裂缝属于非构造性地裂缝。

| Abstract: | The new earth fissures in Longquan village of Jingyang county,Shanxi province appeared in Jan.2007 were surveyed by geological investigation method in field.The result shows,the earth fissures mainly distribute in the both sides of western trench of Qinghui trench,the dislocation of hand wall and foot wall is 5 cm,and they all trend to the water trench.According to the characteristics of geological physiognomy and the changes of seismic precursor observation datum,we analyzed the distribution,characteristics,activity characteristics of earth fissures and the environment near the earth fissures when the earth fissure developed quickly.The result show,because long-term drought,during transportion,the western trench of Qinghui trench leaked,it maked the loess get wet and sink, they are regional geological disaster,they belong to non-structural fissure. |
