Stability Analysis of Surrounding Rock in Deep Underground Engineering Under Fluid-solid Interaction
Academic Journal of Science and Technology, 2023 The geological environment of deep rock masses is extreme and complex, characterized by typical deep geological features such as high geostress, high permeation water pressure, and high geotemperature. Geological disasters like water and mud inrush, high-intensity rock bursts, and large-volume collapses occur frequently in engineering construction ...
