Webb11 sep. 2016 · The effective stress principle, proposed by Karl von Terzaghi in the first half of the twentieth century, is the basis for understanding the mechanical behavior of saturated porous materials [de Boer, 1992].The concept of the effective stress converts a multiphase, multistress porous medium to an equivalent single-phase medium, enabling … 有效应力原理（principleofeffectivestress）这是土力学区别于其他力学的一个重要原理。土是三相体系，对饱和土来说，是二相体系。外荷载作用后，土中应力被土骨架和土中的水气共同承担，但是只有通过土颗粒传递的有效应力才会使土产生变形，具有抗剪强度。而通过孔隙中的水气传递的孔隙压力对土的强度 … Visa mer 太沙基（K.Terzaghi）早在1923年就提出了有效应力原理的基本概念，阐明了粒材料与连续固体材料在应力--应变关系上的重大区别，从而使土力学成为一门独立学科的重要标志。这是土力学区别于其他力学的一个重要原理。土是三相体 … Visa mer 根据这一原理，通常采取加强土体排水措施，促使孔隙水压力消散，以便增大有效应力，达到提高工程稳定性的目的。在岩石力学和地震学中，也有人用 … Visa mer 2.土的变形（压缩）与强度的变化都只取决于有效应力的变化。 Visa mer
