摘　　要：应用细观力学理论中的Mori-Tanaka法和Eshelby等效夹杂法求解了纤维混凝土的弹性模量,对影响纤维混凝土弹性模量的若干参数进行讨论,得出纤维混凝土的弹性模量为砂、石、纤维和水泥(基体)4种组分物理性能和体积率等不同参数的函数。通过比较理论解和已有试验数据可知,二者吻合较好,证明利用细观力学的理论求解纤维混凝土弹性模量是一种可行并有效的方法。The elastic moduli of fiber reinforced concrete were solved by using theory of mesomechanics based on Mori-Tanaka and Eshelby equivalent inhomogeneous method. Some parameters influencing elastic moduli of fiber reinforced concrete were discussed, and the elastic moduli of fiber reinforced concrete were given as a function of physical properties and volume fraction of the following four components： sand, gravel, fibers and cement as matrix. Finally, a comparison was also made between theoretical solutions and published experimental data, and two aspects were in good agreement. It is validated that it is a possible and effective method for solving elastic moduli of fiber reinforced concrete by using theory of meso-mechanics.
