| 摘 要： | 在城市活断层调查中,利用电阻率二维层析成像测量方法,对郯庐断裂带山东潍坊段的地震活断层进行了探测试验,取得了较理想的勘探效果。沂水-汤头断裂、刘家庄断裂的二维电阻率反演结果表明,断裂带两侧的电性结构呈现出整体性的差异,正断层的上盘为低阻区和局部高、低阻扰动区;而断层下盘多为均匀的高阻区;断层为高角度断层。试验探测表明:在城市活断层调查中,选用合适的电极装置类型,电阻率层析成像是一种有效的勘探方法

| Abstract: | The electrical resistivity tomography survey was conducted to detect the active faults along the Tanlu fault zone in Weifang,Shandong province.The results of 2-D resistivity inversion of the Yishui-Tangtou and the Liujazhuang faults indicate that electrical structures on both sides of the fault zone present obvious difference,the resistivity of the hanging wall is low and partially high,while that of the foot wall is high,and the faults are high-obliquity faults.Results show that the resistivity tomography survey is very effective for detection of active faults in urban area. |
