摘要

摘要: 基于Biot波动理论,通过建立饱和地基的热-水-力耦合动力响应的控制方程,对轴对称荷载作用下半无限地基的热-水-力耦合动力响应问题进行探讨。利用Hankel变换技术,得到外荷载作用下地基中温度增量、应力、位移和孔隙水压力积分形式的解答。利用Hankel数值逆变换得到计算结果,对热-水-力耦合条件下地基土体中温度增量、应力、位移和孔隙水压力响应的分布进行分析,并与水-力耦合动力响应情况下的结果进行比较。

Abstract: The dynamic response of a saturated foundation,due to an axisymmetric load,is investigated theoretically by developing the coupling thermo-hydro-mechanical governing equations.The material of foundation,obeying Biot's dynamic poroelastic theory,is idealized as a uniform,fully saturated poroelastic half-space stratum.The analytical solutions of stress,displacement and pore pressure are derived using the Hankel transform and the inverse Hankel transform.Numerical results are obtained and used to analyze the distribution of temperature increment,stress,displacement and pore pressure on the condition of thermo-hydro-mechanical coupling.Further more,the results of hydro-mechanical coupling are compared with those of this paper.
