Abstract

PURPOSE: To improve the earthquake resistance evaluation of an aseismic base isolation joint by putting an inner ring in an annular outer ring having a hook section protruded toward the center of a tunnel, a recessed groove formed in the peripheral direction, and the same shape as the inner ring has and enclosing a damping agent in the space between the rings. CONSTITUTION: A plurality of circular-arcuate bodies having L-shaped cross sections is assembled in a circle and an outer ring 2 is formed of recessed grooves 21 fitted with O-rings 6 and hook sections 22 protruded toward the center of the ring formed of the front ends of the grooves 21 continuously from one side of the assembled body in the circumferential direction. Then an inner ring 3 having nearly the same shape as the outer ring 3 has except the cross section which is inverted from that of the ring 2 is formed and a liquid damping agent 4 is prepared by using a high-quality rubber-based material having a high damping performance. Then a temporarily fixing plate 7 is fitted to the inner peripheral surfaces of the rings 3 and 2 across the rings 3 and 2 with bolts 8 and the damping agent 4 is injected in the space shielded by the O-rings 6 from an injection hole 33. Therefore, the stresses of a tunnel 10 in all directions can be absorbed and relieved.
