Dynamic Stress Concentration Analysis of Multiple Circular Cavities near Multiple Semi-cylindrical Alluvial Valleys
The problem of dynamic response of multiple circular cavities near multiple semi-cylindrical alluvial valleys under incident plane SH-waves is investigated by the methods of complex function and multi-polar coordinates in this paper.Firstly,the solution domain is divided into two parts,Domain Ⅰ is multiple semi-cylindrical alluvial valleys,and Domain Ⅱ is an elastic half space with several subsurface circular cavities near multiple semi-cylindrical alluvial valleys.A series of infinite algebraic equations is then obtained based on the displacement and stress continuity condition on common boundary of two parts after constructing the associated displacement and stresses expressions of each part.Finally some numerical expamples are prensented and dynamic response of subsurface circular cavities near semi-cylindrical alluvial valleys with respect to different parameters is discussed.
