The application of integrated geophysical prospecting methods to the exploration of urban buried fault
-
摘要: 成都市主城区存在多条隐伏断裂,而断裂的准确位置和分布情况尚不明确,这对成都市地下空间资源综合科学开发利用和城市建设规划布局优化造成极大安全隐患。为此,针对工区内的包江桥隐伏断裂采用了微动、高密度电阻率法、瞬变电磁法和土壤氡气测量这4种方法进行综合探测,不仅查明了测线位置的地层结构,而且还获得了包江桥隐伏断裂的位置、性质、产状和规模等参数。本次探测工作表明,采用综合物探方法进行城市隐伏断裂探测可以获得更好的效果。Abstract: The existing geological data show that there are several buried faults in the main urban area of Chengdu. However, the specific location and distribution of these faults are still unclear, which poses great security risks to the comprehensive and scientific exploitation and utilization of underground space resources and the optimization of urban construction planning and layout in Chengdu. In view of such a situation, four geophysical methods, namely, micromotion survey, high-density electrical method, transient electromagnetic method and soil radon measurement, were used in this paper to comprehensively explore the buried Baojiangqiao fault in the work area. The integrated geophysical prospecting methods not only identified the stratigraphic structure along the survey line, but also obtained the location, property, attitude and scale of the buried Baojiangqiao fault. This work indicates that the integrated geophysical prospecting methods can achieve better results in the exploration of urban buried fault.
