Study on anti-impact support structure performance of multi-direction energy absorption for roadway

Aiming at the problem of insufficient impact resistance of the existing portal support, a kind of anti-impact support structure for multi-direction energy absorption was constructed by adding V-shaped groove to the beam structure and flexible chain support structures on both sides. Parameters such...
