| 摘 要： | 在理论上，利用O‘Connell的饱和水裂隙岩体等效弹性模量与岩石模量的关系式，并由式中的裂隙密度概念意义，建立了温度作用下的裂隙密度与Oda提出的裂隙张量之间的关系式；在试验的基础上，给出了温度、饱和水下的单裂隙岩体应力－应变、抗压强度回归拟合关系表达式。并通过试验与拟合结果对以加以验证，其裂隙岩体力学模型可为裂隙岩体THM耦合分析提供合理的依据。 |

| Abstract: | The mechanic function is theoretically described with the relationship between effective elastic moduli of saturated cracks of jointed rock mass and elastic moduli of rock, derived by 0?Connell. According to the implication of the crack-density parameter in the relationship, the mathematical relationship is derived between the crack-density and the fracture tensor introduced by Oda under temperature effect. On the basis of the experiment results, under the effects of temperature and saturated water the regression expression of stress-strain and the compressive strength are obtained for the rock mass with single joint. The model is demonstrated by the results of test. The mechanical model can be used for THM coupling analysis on jointed rock mass. |
| Keywords: | mechanical behavior of jointed rock mass crack tensor crackdensity elastic moduli |
