Research on Stability of Utralong and Deep-Buried Tunnel Surrounding Rocks Based on GA-GRNN Geostress Field Inversion
According to the geological condition and measured geostress data of the utralong-distance water diversion project,a 3D inversion calculation model of the initial Tennis Balls geostress field of the water diversion route was established.The initial geostress field of the water diversion route was exactly simulated through the method of generalized
