SV波入射下衬砌尺寸对引水隧道动力响应的影响
Influence of structure size on water diversion tunnel's seismic response induced by SV wave
摘要
Abstract
The Fourier-Bessel series expansion method is used to obtain the analytical solution of large-scale water diversion tunnel's seismic response induced by plane SV wave. The numerical results of the model are obtained by using the analytical solution. The research results show that both the dynamic radial stress and dynamic tangential stress of water diversion tunnel lining increase as the tunnel radius increases, and the maximum of dynamic radial stress is proportional to tunnel radius. Moreover, tunnel radius has a significant effect on dynamic tangential stress when the incident angle is less than the critical angle. In addition, dynamic radial stress increases and dynamic tangential stress decreases as the increase of lining thickness.关键词
