Scientists developed a terahertz microscope that compresses terahertz light down to microscopic dimensions. This pinpoint of terahertz light can resolve quantum details in materials that were previously inaccessible. 

The research focused on the Hankou Tunnel, a deep-lying section of the challenging Xinjin Expressway spiral tunnel group. To find the best way to support the tunnel walls, the research team turned to advanced computer simulation technology (using the ABAQUS platform). Researchers created detailed digital models to simulate the entire construction process from start to finish. Published in Smart Construction, the findings offer crucial reference for designing more effective support systems for other deep mountain tunnels built in similar rock formations.
