饱和多孔介质的热固结理论

THEORY OF THERMO-CONSOLIDATION FOR SATURATED POROUS ELASTIC MEDIA

本文严格地从混合物理论出发,详细地推导出了描述饱和多孔介质在热合固结耦合作用下性状的方程.作研究的混合物为温度单一和可混溶体,固液两相均为热弹性线性状态,且没有化学因索鑫与.本文的结果为研究热固结问题提供了理性基础和实用性方程.本文还对耦合效应、组分的可压缩性以及有效应力等概念进行了讨论,得出了一些有意义的结论.做为应用实例,本文还指出热固结问题的一般解法,并给出球对称加热情形的解析解答.

In this paper is presented, rigotously based on theory of mixtures, the constitutional equation for saturated porous media under coupled effect of heat and consolidation. The mixture studied is one of montonnous temperature, whose ingredients are mutually insoluble, both solid and liquid phases being linearly thermo-elastic, with no chemical factors brought into play reasult of the studies give rise to a rational basis and equation for practical use. In this paper is also presented a discussion of the concepts of compressibility and effective stress, as component parts of the coupled effect, and arrived at conclusions which may be of significance. Geneal solution of the problem is also given, with the analytical solution for the case of sphero-symmetrrical heating, as an example.
