| 摘 要： | 归纳了煤矿软岩巷道变形破坏的非均一性的表现形式，从地质工程角度分析探讨其产生的原因。认为软岩巷道变形破坏的非均一性与软岩及其环境的非均一性和工程因素有关，是这些因素导致巷道软岩力学行为过程与支护结构体系力学行为过程不相适应、非耦合之故。文中总结了相应的控制对策，指出多种对策的有机结合的必要性,强调要正确使用这些技术对策，必须首先对巷道工程地质进行细致研究，要全面掌握巷道工程地质条件，掌握软岩的力学行为特征。强调支护设计要遵循大变形岩土工程设计的思想与原则。

Non-homogeneity of the
deformation and failure of the tunnel within weak rockmass and its controlling
countermeasures |
| |
| Abstract: | The modes of non-homogeneity of the deformation and failure ofthe tunnel within weak rock mass are summed up. The cause of the non-homogeneity is analyzed with geo-engineering view. The analysis indicates that the non-homogeneity associates with the non-homogeneity in aspect of both weak rock mass and its environment, construction factors，which cause supporting system not to match with deformation process of weak rockmass. Then some corresponding controlling countermeasures are summarized in the paper. The necessity of uniting some countermeasures is pointed out. In order to use correctly these countermeasures, it is stressed that the engineering geology must be firstly used in researching in detail, and that the engineering geological condition, mechanical characteristics and behaviors of weak rock should be mastered. It is also emphasized that the geotechnical design thinking and principle under the condition of large deformation must be followed during design of supporting. |
