Fundamental Solution of Ground Vibration Based on Thin-layer Stiffness Matrix Method

摘要：

A semi-analytical method is developed based on the thin 4ayer stiffness matrix method ,to obtain the stationary fundamental solution of elastic layered half-space soil. The Fourier series expansion about polar angle ,the Hankel transformation to space and its inverse transformation in cylin -drical coordinate are applied to dynamic equilibrium. The dispersion curves , cutoff frequencies, modal displacement, and fundamental solution of ground stationary vibration are discussed by examples for two types of soils. The results show that the approach is feasible and effective and dynamic char acteristics of soil layer have influence on ground vibration greatly.
