Seismic Behaviour Of Tunnels In Random Soils By The SBEM
Author(s)
C Z Karakostas & G D Manolis
Abstract
A stochastic boundary element method (SBEM) is developed for evaluating the response of tunnels i n random soils excited by seismically-induced SH waves. A series expansion for the Green's functions is employed, where the basis functions are orthogonal polynomials of a random argument. These functions are subsequently incorporated in a SBEM formulation. The proposed methodology is then used for the solution of problems of engineering interest involving tunnels. Finally, the present approach is valid for an arbitrarily large amount of randomness in the soil medium.
