| 摘 要： | 楔形刃压头与岩石作用规律的研究是全断面岩石掘进机研制的基础理论.通过对楔形刃压头贯入岩石产生的现象及其与岩石相互作用规律的研究,发现在楔形刃作用下,岩石破坏的宏观表现是“跃进破碎”.岩石在跃进破碎前经历弹性变形和塑性变形,弹性变形较小,塑性变形在跃进破碎前及两相邻跃进破碎间是岩石变形的主要形式,并且作用在楔形刃上的力与...

| Abstract: | The research on the interaction between the Wedge-shaped blade head and the rock is not only the theoretical basis for developing TBM,but also the research focus of scholars at home and abroad.The study of the phenomenon of the Wedge-shaped blade head's piercing the rock and the interaction between them reveal that under the effect of the Wedge-shaped blade Head,the macro form of rock-breaking is jump crushing. Before that,the rock undergoes elastic deformation and plastic deformation.The rock deformation i... |
