| 摘 要： | 红层软岩的物质组成、化学成分、物理力学性质等方面在国内外已有较系统的研究,但对软岩隧道围岩的变形破坏机理及其治理一直是工程技术人员关心问题。通过对回龙宫隧洞的地质环境分析及有限元数值计算,阐明了红层隧洞围岩的膨胀变形破坏机理,最后提出了在此类围岩中修建水工隧洞的过程中,防止围岩变形破坏的建议。

| Abstract: | The properties of red-bed soft rock have been systemically researched beth domestically and abroad, these properties include the material constitution, chemical ingredient and physical-mechanical property. But engineer and technician pay more attention to the mechanics of deformation and failure as well as the treaunent to such deformation and failure. Based on the geological environment analysis and finite element numerical calculation of the HuiLongGong tunnel,this paper explains the mechanics of deforming failure result from the swelling of the red-bed soft tunnel's surrounding rock. Finally recommendations for preventing deforming failure of such hydraulic tunnel are presented in this paper. |
