实驗资料表明,混凝土和岩石都是透水的多孔結构,渗透水对其应力状态有重要影响.文献[5～7]曾对均貭重力坝的渗透应力进行过研究,但实际上重力坝往往是非均质的.在非均貭重力坝內,布拉茲(J.H.A.Brahtz)理論不再适用,卽使渗透压力滿足調和方程,但有效应力并不等于不透水坝体的应力与渗透压力之差.本文将根据渗压-应变关系,研究渗透水对非均貭重力坝应力状态的影响. Experimental data show that both concrete and rock are permeable and porous structures, and infiltrated water has an important influence on the stress state [5 ~ 7]. The infiltration stress of the average dam has been studied in literature [5-7] Homogenous. In the non-uniform gravity dam, the theory of JHABrahtz is no longer applicable, and the osmotic pressure satisfies the harmonic equation, but the effective stress is not equal to the difference between the stress and the osmotic pressure of the impervious dam. In this paper, we will study the influence of seepage water on the stress state of a non-uniform gravity dam based on the seepage-strain relationship.
