| 摘 要： | 在现场调查的基础上,通过对西南某电站地下厂房洞室群围岩岩体质量的分析评价,采用三维有限元数值分析方法,对比分析不同岩体质量条件下,洞室开挖后围岩的二次应力场、变形场和塑性破坏区的差异。较全面地讨论了岩体质量对地下洞室围岩稳定性的影响。

| Abstract: | In this paper, taking the underground cavities of a planned hydroelectric station located in Lancang River as an example, three-dimensional finite element numerical modeling technique is used to analyze systematically the distribution features secondary stress field, displacement field and failure zone in the surrounding rockmass of the underground cavities after the excavation when the surrounding rockmass quality rank change from Ⅱ to Ⅳ. The influences of rock quality on excavation effects are discussed in detail. |
