    电法精细探测在雄安新区的应用展望

    APPLICATION AND PROSPECT OF FINE DETECTION IN XIONG-AN NEW AREA BY ELECTRICAL METHOD

    • 摘要: 从国家建设雄安新区的目的标准及措施看,对浅层地球物理的探测标准和水平提到了史上最严、精度最高的世界级标准。为此,本文对电法勘探中的高密度电阻率法及中国科学院自主研发的多通道大功率电法系统这两种方法进行了对比与总结,并对这两种方法在雄安新区的应用和进一步创新进行了展望。由于这两种方法都采用仿反射地震勘探方法的布极方式,一次性布设电极,通过改变电源的位置,得到一条剖面下由浅到深多个点的高密度电法资料,因此,横向分辨率都较同类方法高。通过这两种方法相结合的方式,可获得由浅入深不同垂向分辨率的电法资料,从而实现电法的精细探测,有望为雄安新区建设中遇到的水文、地质构造等勘查任务提供物探方法支撑。

       

      Abstract: The strictest criteria for shallow electrical exploration method are up to the world level, because the criteria and measurement to develop of Xiong-An new area is laid down by China. Therefore, this paper sums up and compares two electrical methods. They are the high density resistivity method and the Multi-Channel powered electric system. Both are developed by Chinese Academy of Sciences. Both are expected to be used in the development of Xiong-An new area. The two methods can get higher horizontal resolution data than those obtained by other electric methods due to the similar configuration as the reflect seismic method. That is, laying down all of the electrodes along the survey at the same time, and collecting density data from shallow to deep through moving the transmitter. Therefore, the integral of these two electric methods can achieve fine electrical detection, and can provide high vertical resolution geophysical data for the hydrology and geology exploration task in developing Xiong-An new area.
