英文摘要Evaluation of rock mass quality is necessary for the proper design of engineering infrastructures. Rock quality designation (RQD) is an important geotechnical parameter in the rock mass quality classification. However, given the limited data and natural heterogeneity, rock mass quality evaluation is a challenging task. Traditionally, the rock mechanical parameters are obtained from the drilling tests. However, the drilling tests only provide single-point information and thus cannot provide detailed underground information. Moreover, boreholes are costly and time-consuming, and still cannot be carried out in the steep topographic terrains. Alternatively, electrical resistivity tomography (ERT) is non-invasive, cost-effective, and user-friendly, can provide 2D plane information even 3D information, and can bridge gaps between the available well data and the accurate subsurface geological model. In this research, we establish important empirical relations between ERT and the limited borehole data. We estimated RQD along with the ERT profiles and evaluated the subsurface for rock mass quality even where no borehole exits. Furthermore, the ambiguity of water/clay distinction in the geological model was removed via integration between ERT and induced polarization. Compared with the past geotechnical studies, our work provides far better insights into the subsurface via 2D/3D evaluation of rock mass quality for the development of the engineered structures. Therefore, geophysical research based on ERT can be very helpful in the hard rock terrains lacking sufficient mechanical well data. Plain Language Summary The success of engineering infrastructures in the hard-rock terrains mainly depend on the foundation rocks, which provide necessary bearing support for the structures. The bearing capacity of foundation rocks is classified by the geotechnical parameters, such as rock quality designation. Such parameters, however, are acquired from drilling tests. Such tests have limitations, and cannot be conducted to cover large area. Therefore, it is essential to reduce significantly the number of costly boreholes, and reliably to evaluate the rock mass quality for proper infrastructure design in order to bring a sigh of relief to the planners and experts. Conversely, use of geophysical methods is non-invasive, inexpensive and user friendly. In this contribution, we propose that few drilling tests could be performed at certain essential locations, whereas geophysical survey (e.g., ERT) would be acquired along various profiles to cover the entire area. The selected ERT data points near the available boreholes would be integrated with the rock mass quality parameters determined from drilling tests. Afterward, the geotechnical parameters would be obtained from the established empirical equations for all ERT data points, and thus the entire area is investigated thoroughly (vertically and laterally) where even no borehole exists.
