构造应力作用下软岩巷道变形与控制研究

Deformation and its control of tunnel surrounded by weak wallrock under condition of textural stress

通过建立围岩变形破坏的力学模型 ,对构造应力区软岩变形破坏特征、力学机制、应力转移过程模式进行理论研究分析计算 ,提出了支护控制准则 ,为软岩巷道控制提供了依据。

By means of mechanics model about wallrock deformation and break,the feature and mechanism of deformation or break of weak rock under textural stress and the mode of stress transfer are theoretically analysed and calculated.The results of analysis and calculation are the basis for determining the principle of propping the tunnel surrounded by weak wallrock.
