岩溶隧道在SH波激励下动力响应位移解析解
Displacement analytical solutions of dynamic response of karst tunnel subjected to SH waves
摘要
Abstract
Based on the engineering wave theory,displacement analytical solutions are derived for the dynamic response of a karst tunnel subj ected to SH waves with the wave function expansion method and Fourier-Bessel series transformation,and a practical simplified solution is proposed.The rationality of which is verified by numerical simulation solution.The differences of displacement amplitude peak value of the karst cave and the tunnel are about 10% between the two methods when the incident angles are 0°and 90°.The dynamic response effects of three factors,such as the radius of karst cave,the incident angle of plane SH wave and the center distance between karst cave and tunnel,are studied.The results show that the displacement amplitude values of the karst cave and the tunnel are proportional to the radius of karst cave,are inversely proportional to the center distance between the karst cave and the tunnel,and are proportional to the plane SH wave incident angle.关键词
