Study on seismic ground motion of P-wave incident elastic foundation free field under thermal effect
This study extends the traditional problem of a seismic response of elastic foundations under isothermal conditions when considering thermal effects. Firstly, a free-field model of the elastic foundation is established under the incidence of plane P -waves. Then, utilizing the principles of wave propagation in a homogeneous and isotropic thermoelastic medium and the principle of Helmholtz vector decomposition, the influence of thermal physical parameters such as thermal conductivity, medium temperature on seismic ground motion of the free--field on elastic foundation is investigated, which provides a reasonable explanation for the ground motion of a site under thermal effects.
