| 1. | Analysis of the method of underground development across the destructive zone resulted by local small mines 穿越小煤窑破坏区开拓方式分析 |
| 2. | The problem concerning the occurrence of high intension belt caused by 1975 haicheng earthquake with m ( subscript s ) 7 . 3 is discussed in this paper 文章还就鞍山市在1975年海城7 . 3级地震中严重破坏区的形成原因作了讨论。 |
| 3. | If untreated , the blood and the exudation accumulated over the macular region will damage the photoreceptor cells over there and eventually cause irreversible visual loss 若不妥善处理,血液和渗出物会于黄斑区积聚,破坏区内的感光细胞,最终导致不能弥补的视力受损。 |
| 4. | If untreated , the blood and the exudation accumulated over the macular region will damage the photoreceptor cells over there and eventually cause irreversible visual loss 若不妥善处理,血液和渗出物会于黄斑区积聚,破坏区内的感光细胞,最终导致不能弥补的视力受损。 |
| 5. | And that , the variable regulations of stress field , strain field and plastic failure zones in the surrounding rock mass of the underground cavities are summarized for the right and the left bank of underground chambers 全面总结了溪洛渡水电站左、右岸地下厂房洞室群围岩应力,变形和破坏区的分布特征和变化规律,为洞室群稳定性评价和工程施工设计提供了基础资料和理论依据。 |
| 6. | When combined method is applied , damaged area develops from down stream to up - stream , besides , controlling effect of discontinuous joints is shown . at normal storage water level , the combined safety factors are 4 . 05 and 3 . 75 for 9b and 4b respectively 结果表明,超载法时,破坏区从上游向下游发展,且破坏前锋一直沿建基面附近;综合法时,破坏区从下游向上游发展,并表现出裂隙结构面参数的控制作用。 |
| 7. | And the variation characteristics of stress field , strain field and plastic failure zones in the surrounding rock mass of the underground cavities are summarized , which provides basic information and reference for the evaluation of underground cavities stability and project construction 总结了地下洞室群围岩应力、变形和破坏区的分布特征和变化规律,为洞室群稳定性评价和工程施工设计提供了基础资料和参考依据。 |
| 8. | Based on the simplified structure of rock mass , three - dimensional finite element numerical modeling technique is used to analyze systematically the distribution features of filed , strain field and plastic zone in the surrounding rock mass of the underground cavities after the excavation 在岩体结构模型概化的基础上,采有三维有限元数值分析方法,系统研究了大跨度、高边墙地下洞室群开挖完成后围岩的二次应力场、变形场和塑性破坏区的变化特征。 |
