摘要
在工程范围内,复合岩体可视为各向同性的均质岩石单元,从而可运用等效本构论理和弹塑性理论导出复合岩体等效弹塑性本构关系的计算方程。将本构方程计算结果与单轴抗压强度试验进行对比,表明二者是较为吻合的,因而验证了所导出的本构关系的合理性和有效性。
In a sense of engineering, composite laminary rockmass is considered as isotropic homogenitic rock element so that equal-effect constitutive theory and elast-plasticity theory can be used to derive the calculation equation for equal-effect elast-plasticity constitutive relation of composite rock-mass. A comparison between calculation results and test results of uniaxial co-mpressive strength indicates that they are in good agreement, thereby verifys the rationality and effectness of the mathematical simulation of this constitutive relation.
