An Analytical Solution for Dynamic Stress Concentration of Underground Lined Cavities under Incident Plane SV Waves in Different Angle and Frequency

摘要：

An analytical series solution for dynamic stress concentration of underground lined cavities under incident plane SV waves is given by wave function expansion method. The infinite series is cut and calculated under the required precision. The lining includes rigid lining, unlined cavities, flexible lining. The numerical results show that the angle of SV waves plays an important role in the dynamic stress concentration; With the increasing of the wave frequency, the distribution of dynamic stress concentration becomes complicated; The interaction between two cavities greatly amplifies the dynamic stress concentration; The rigidity of lining also has great effect on the dynamic stress concentration which is highest for the rigid lining, second for unlined cavities and is lowest for the flexible lining.
