Latest Patents

Guan is credited with 1 patent: “True Triaxial Dynamic Disturbance Test Device for Deep-Buried Hard Rock.” The device combines a rigid static-load assembly, which applies sustained force to a rock sample, with a rigid dynamic-load assembly that applies disturbance stress. Its design enables the coupled application and control of long-duration static force and dynamic disturbance in a true triaxial stress state.

A disturbance rod, disturbance hole, and sample clamp convert a point disturbance into a face disturbance. This approach is intended to better represent conditions encountered in the field while reducing power consumption and enabling time-dependent dynamic disturbance testing.

Career Highlights

Guan’s listed invention addresses experimental testing of hard rock under complex loading conditions. By combining sustained static loading with controlled dynamic disturbance, the device provides a way to investigate rock behavior in settings relevant to deep underground engineering.
