| 摘 要： | 在岩体加、卸荷试验研究的基础上，从应力－应变关系、强度特性、声发射及破坏特征等方面，对岩体在加、卸荷条件下的破坏特性进行对比分析。结果表明：同类型的岩体在相同的主差应力作用下，卸荷产生的扩容量比加荷的更大；卸荷破坏的强度比加荷的更低；卸荷产生的声发射率比加荷的更高；加荷下岩体易呈剪切破坏特征，而卸荷下岩体常呈张剪复合型破坏特征。

| Abstract: | Deformation and failure may take place in rock mass under loading or unloading conditions, and their various characteristics can be shown. On the basis of the failure experiment results of rock mass models or rock specimens, a comparison of stress-strain relations, strength characteristics, acoustic emission rate and fractured forms of rock mass is made respectively under loading and unloading conditions. |
