Abstract:In recent years, the high-density resistivity method has been widely used in geological exploration and the evaluation of the stability of important project sites. In this paper, the high-density resistivity method and other methods were adopted to evaluate the seismic stability of the ADS facility site, a large-scale scientific facility project in China. This ADS facility is located in Huidong County, Huizhou City, Guangdong Province. Several high-density electrical profiles were developed for the site area, and resistivity profiles were drawn after two-dimensional inversion. Combined with the existing borehole and geological data, the distribution characteristics of the underlying faults were inferred and interpreted, followed by the investigation of the fault occurrence, thickness of the weathering layer, and hydrogeological conditions. To provide technical support for the design and construction of devices at the proposed site, we also studied the possible earthquake damage amplification of the faults near the site from future earthquake action. This comprehensive evaluation method can serve as a reference framework for the selection of similar sites for major national projects.
