Application of Integrated Geophysical Methods for Site Suitability of Research Infrastructures (RIs) in Mountain Area

Research Infrastructures (RIs) are significant for innovative scientific research worldwide. However, given the limited land use and strict geological requirement, reliable evaluation of a suitable site for a new RI is a challenging task. How to better understand and evaluate the suitability, availability, factor controllability, and engineering adjustability of sites under different conditions from the perspectives of hierarchy, correlation, and timeliness is a more specific and practical task for engineering geologists. In the process of selecting and evaluating the 9 major scientific facility sites, including the Daya Bay Neutrino Experimental Tunnel and the China Spallation Neutron Source Site, this research proposed a geological engineering evaluation and dynamic control method based on three support points: One rock, one view, and one method. The aim is to focus on controlling structural elements and delineating unfavorable geological bodies, adjusts the engineering layout plan in a timely manner, and propose construction suggestions related to the boundary range and disturbance intensity of site renovation, realize rational and harmonious regulation of geological engineering. Among them, the integration of geophysical methods for high dimension description of exploration results is very important.
