| 摘 要： | 地震灾害表明活动断层是产生地震的根源,且沿断层破坏最为严重。高密度电阻率法(HDR)、地质雷达(GPR)和瞬变电磁法(TEM)等方法在长春市的活断层试验探测工作中,结合城市内干扰背景强、干扰因素多和地表地质条件复杂等不利因素,通过对不同方法、不同数据处理过程和解释,选择有效的方法技术,取得了较理想的探测效果。结果表明,在长春市活断层调查中,电法是探测隐伏断裂既经济又有效的重要手段。

| Abstract: | Seismal calamity indicales that alive fault is the source of causing seism and destruction is most serious along fault line.This article introduces the electrical prospecting ways which include high density resistivity(HDR),geology purpose radar(GPR),temporal electromagnetism(TEM) and so on are used to testing and prospecting the alive fault in Changchun city.Considering the unfavourable factors in the city which include the intense disturbance background,numerous disturbance factors,complex geology condition on the surface of the earth and so on by different means and different data processing circuits effective techniques and methods are selected and ideal prospecting results are achieved.The result indicates that electrical prospecting is a economical and effective means for prospecting hidden fault in alive fault investigation in Changchun City? |
