摘　　要：本文从贝蒂(Betti)定理出发,考虑裂隙在压剪应力作用下的闭合效应,推导出有序多裂隙岩体的本构方程,同时采用数学弹性力学的方法,精确推导出传压系数的理论公式,并对传剪系数加以分析。On the foundation of Betti' s theorem,the constitutive relation of multi-crack rockmass which considers the effect of crack-closure is developed in this paper.Meanwhile,based on mathematical elastic mechanics,this paper gives the theortical formula of compression transferring coefficient,and also analyses shearing transferring coefficient.
