摘要
本文讨论了应力的理论构成,提出了应力确定性模型和混合模型的形成方法,导出了因子的形成和相应系数的物理意义,认为应力确定性模型不仅能反求相应点的热膨胀系数,亦可估计大坝的整体弹模和热膨胀系数。实例表明:建立应力的确定性模型和混合模型是可行的,有实际意义的。
The fundamental principle, method and formulas are presented to set up the dcterminitic model and hybrid model of stress. One water pressure factor and two temperature factors are formed and the parameters are discussed. It is shown that, not only the integrative elastic modulus and thcmo-coefficient of expansion, but also the themo-coefficient of expansion at points, can be obtained from the determinitic model of stress. An example is given to introduce the whole procedures of the establishment of the dcterminitic model, hybrid model, and inverse analysis. It is proved that the stress models are valuable and reliable.
