AI Technical Summary
Existing technologies make it difficult to accurately assess the reinforcement performance of anchor bolts in freeze-thaw environments. There is a lack of effective methods to uniformly simulate random cracks, anchor bolt support, and freeze-thaw coupling, resulting in the inability to accurately assess the reinforcement performance of anchor bolts in freeze-thaw environments.
Using the smooth particle hydrodynamics theoretical framework, a full-process simulation method for freeze-thaw cycle, phase transformation, stress, damage, and anchoring is constructed. By discretizing the rock mass and anchor bolt into particles, pairing them using smooth kernel functions, constructing a set of governing equations to calculate simulation information, and identifying damaged particles during the failure process, the interaction force between the anchor bolt and the rock mass is simulated.
It enables accurate analysis of the stability and anchoring effect of randomly fractured slopes under freeze-thaw conditions. The mechanical parameters in the calculation model are easy to calibrate, reducing the complexity of model calibration and improving calculation efficiency, thus providing a tool for long-term stability assessment of large-scale rock slope engineering.
