| 摘 要： | 以高密度电阻率法为主,综合其他方法对"十二五"国家大科学装置项目——ADS项目的场地稳定性进行评价。ADS项目场址位于广东省惠州市惠东县,通过在场区布设多条高密度电法剖面,进行二维反演后绘制电阻率剖面图,结合已有的钻孔和地质资料对其下断层的分布特征进行推断解释,查明场区内的断层产状、风化层厚度、水文地质条件等;并对厂址附近断层在未来地震作用下可能放大震害的问题进行研究,为拟建场区装置的设计和修建提供相关的技术支持。这项综合手段的评估研究可为同类国家重大项目选址时提供参考。

| 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. |
