摘要: This paper presents an analysis of the rocking vibrations a rigid cylindrical foundation embedded in poroelastic soil. The is subjected to time-harmonic excitation and perfectly bonded surrounding soil underlying base represented by homogeneous half-space, whereas along side modeled as independent stratum composed series infinitesimally thin layers. behavior governed Biot's poroelastodynamic theory. contact surface between assumed be smooth either fully permeable or impermeable. dynamic interaction problem solved employing simplified analytical method. Some numerical results for nondimensional impedance angular displacement amplitude are presented show effect frequency excitation, material parameters, hydraulic boundary condition, depth ratio mass foundation.
