【摘要】 在韩城市龙亭镇开展了高密度电阻率法和放射性能谱地裂缝探测工作。以电阻率差异和放射性差异为基础,综合两种方法推断了区内主要的裂缝发育情况及延伸方向,划定了地裂缝危险区,其与地面裂缝调查结果具有较好的吻合。经推断认为,区内的地裂缝是NE向大型隐伏构造断裂与河岸边坡滑塌双重作用的结果。探测结果表明,综合物探方法在探测地裂缝时效果明显,而且具有方便、快捷的特点。更多还原

【Abstract】 The detection of ground fissures was carried out by using the high density resistivity method and radioactive energy spectrum technology in Longting Town of Hancheng City.To achieve the purpose of detecting fissures,the authors used the difference between the resistivity method and the radiological method to deduce ground fissures of this area,delineate the hazard zones,and select a reasonable relocation range.In this area,the ground fissures resulted from the double influence of the NE-trending large-size concealed structural faults and the slope collapses of the river bank.The detection results show that the integrated geophysical methods have the advantages of effectiveness,convenience and rapidness in the detection of ground fissures.更多还原
