【摘要】 高应力软岩巷道具有持续塑性变形破坏特征 ,单一支护方式难以控制。通过建立围岩变形破坏的力学模型 ,对高应力软岩变形破坏特征、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 ,工程实例中控制了巷道强烈变形 ,保持了巷道的稳定 ,为高应力软岩巷道控制提供了依据更多还原

【Abstract】 Soft rock roadway has the character of continuous plastic deformation. It’s difficult to control using the single supporting way. It has engaged in theory study and analysis calculation on soft rock deformation character in high sress and mechanics mechanism and model of stress divert process and advanced supporting control criterion by way of establishing mechanics model of round rock deformation.the violent deformation of roadway has been controlled in the practice.Steady of roadway has been kept. It has supplied basis for controlling soft rock roadway in high stress.更多还原
