Initiation Mechanism of Unsaturated Rock Cracks Driven by Ice–Gas–Heat Flux Coupling During Freezing

In high‐altitude cold regions, ice–water phase change during freezing expands ice and compresses trapped gas in unsaturated rock cracks, whereas temperature gradients induce thermal stress, jointly driving crack initiation. This study derives governing equations for ice–gas mechanics, establishes stress intensity f...
