DYNAMIC RESPONSE OF CIRCULAR FOOTINGS ON SATURATEDPOROELASTIC HALFSPACE

摘要

The dynamic responses of footings on a saturated poroelastic half space and subjected to horizontal andrnrocking harmonic excitation are studied. By treating the footing as a rigid disk, the problems for vibrationsrnof disk on poroelastic half space are formulated to Fredholm integral equations of the second kind whichrnare solved numerically. The compliance coefficients for the horizontal and rocking vibration of disk arernpresented to illustrate the dynamic characteristics of footings on a poroelastic half space.
