摘要

本研究扩展了传统的等温条件下弹性地基的地震反应问题,同时考虑了热效应。首先,建立了平面纵波作用下弹性地基的自由场模型。然后,利用均匀各向同性热弹性介质中的波传播原理和亥姆霍兹矢量分解原理,研究了热导率、介质温度等热物性参数对弹性基础上自由场地震地面运动的影响,为热效应下场地的地面运动提供了合理的解释。

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.
