Research on Earthquake Resistant Materials in Mountain Tunnels Crossing Fault

Abstract:

Seismic damage, such as falling, fissure and dislocation of the lining may happen at location of fault movement. The model of enhancing stiffness and that of adding seismic decrease layer are built by the finite element software MIDAS to compare the two earthquake-resistant methods. Some useful results are obtained: a)The displacement is decreased, but the peak acceleration and first principle stress of the lining are increased in the model of enhancing the lining materials stiffness. b) The displacement, peak acceleration and first principle stress are all decreased in the model of adding seismic decrease layer. c) The max-displacement when using c20 as lining material or adding seismic decrease layer is in the area of fault, but that of the model when using c40 as lining material is in the area of entrance.
