Abstract

The nonlinear mechanical behavior and response of deep rocks is essential for disaster mechanism revelation and accurate stability prediction. This study summarizes the principal outcomes from Session 50 of the second “International Geo-Energy Frontier Forum”, entitled “Nonlinear Mechanical Behavior and Response of Deep Rocks.” A total of 16 experts and scholars presented at the session, which covered a broad spectrum of topics in deep rock mechanics. Centering on the rock mechanics challenges in deep energy resource development and underground space utilization, this session synthesized research advances in anisotropic mechanical behavior, fatigue damage evolution, nonlinear strength criteria, and fracture mechanisms coupled with hydraulic synergistic control, and then outlined future research directions for deep rock mechanics. The perspectives presented were intended to provide theoretical and technical support for the safe and efficient development of deep earth resources.
