DEF

Steel arch installed in underground openings as the ground is removed.

OBS

... [Steel arches] are employed to support loads caused by changing ground movement or faulted and fractured rock. They are designed so that when the ground load exceeds the design load of the arch as installed, yielding takes place in the joint of the arch, permitting the overburden to settle into a natural arch of its own and thus tending to bring all forces into equilibrium. The arch is stronger after this yielding than before because of increased joint overlap.

PHR
