摘要
论述了深部岩石力学与工程问题研究的意义;评述了深部原岩应力分布对岩石性质与岩石工程的影响;指出了岩石强度失效与工程围岩破坏过程的实质;分析和评价了岩石破坏所形成的序列结构形式以及对其强度的影响.根据深部岩石工程施工以及变形破坏的特点,通过对工程开挖的卸压影响、岩石脆性与延性破坏的关系以及岩石变形、破坏的时间效应的分析,说明了深部岩石工程稳定有其不同的性质与特点.
The significance of the research on rock mechanics and engineering was indicated in great underground depth. The effect of distribution of the initial stress on rock quality and rock engineering was evaluated. The essential of the failure for rock strength and surrounding rocks of engineering is represented. The structural sequence formed from the failure of rock and its effect on the rock strength were analyzed. Based on the situations of the deep rock engineering construction and its deformation and failure, it is explained that there are diverse property and peculiarity for the stabilization of the rock engineering in deep underground, by analyzing the unload effect during the engineering construction, the relationship between the brittleness failure and ductile failure of rock, and the time effects of the deformation and failure of rock.
