Anti-seismic supporting structure of underground building

The invention discloses an underground building anti-seismic supporting structure, and belongs to the technical field of anti-seismic supporting, the underground building anti-seismic supporting structure comprises a supporting column part, a plurality of energy absorption boxes are arranged in an inner cavity of the supporting column part in the width direction and the length direction, the adjacent energy absorption boxes are connected through prestressed twisted ropes, and the tail ends of the two sides of the supporting column part in the width direction are connected with supporting pieces; the two sides of the supporting piece are connected with the prestress twisted rope, and the two sides of the energy absorption box are detachably connected with protection assemblies. In the invention, the prestressed twisted ropes and the energy-absorbing blocks can utilize elastic force to reset and maintain the supporting capacity to the peripheral structure, so that the energy-absorbing effect of the strut part u
