| 摘 要： | 针对目前切眼围岩破坏的问题，对切眼围岩类型进行总结，得出切眼围岩的基本模型。为求解切眼围岩的破坏原因，运用自行开发研究的岩石破裂过程分析(RFPA^2D)系统，对切眼围岩破坏过程进行了数值模拟研究，通过对切眼围岩的初始裂缝形成、发展及最终破坏模式进行分析，得出不同条件下切眼围岩的破坏规律。结果表明，切眼由于其断面形状和围岩组成结构的不同关系，其破裂结果与其他巷道破坏模式明显不同。

| Abstract: | In view of the destructional problem of open-off cut, the type of open-off cut surrounding rockmass is summed up and the basic model of open-off cut surrounding rockmass is obtained. In order to know the destructional cause of open-off cut surrounding rockmass, this paper with rock failure process analysis (RFPA2D) system, simulates the destructional mode of open-off cut surrounding rockmass, by analyzing the initial crack forming, developing and the last destructional mode of open-off cut , which gets the destructional law of open-off cut surrounding rockmass. This result of numerical simulation indicates the destructional result of open-off cut is different from other galleries because of the relation between the cross shape and surrounding buildup configuration of open-off cut. |
