The safety of the support system is a crucial component of construction safety and a particularly dangerous sub-project above a certain scale. The greatest hazard to the support system is overall instability, damage, and overturning. Among the bearing capacity factors of the entire support system, external corners present the greatest safety risks due to their structural form, pole arrangement, and relatively long length.
