摘要
Sesmic dynamic response of Fiber Reinforced Concrete tunnel lining is studied in contrast to the plain concrete. Based on similar theory, model test has been carried out through the 5mx5m triaxial shaking table by inputting sesmic wave, then the damage characteristics of tunnel lining is acquired.The test results show that both the plain concrete and fiber concrete is brocken by sesmic load, but fracture form is not the same,the crack on Fiber concrete is narrow and sawtooth, the crack on plain concrete is wide and straight.Fiber concrete lining strain-time curve is sawtooth partly, it's vibration reponse is a little lagger than that of plain concrete.It indicats that kinematic velocity of concrete granule is decreased and sesmic energe is absorbed by fiber cohesive force,then frequence amplitude can be reduced.So fiber concrete can be proved as fine anti-seismic material.
