地下工程的喷锚支护技术具有许多优点,但由于对它的工作机理研究得不够,目前还形不成一套完整而科学的设计方法,因而使这项技术的推广应用受到一定的影响。陶振宇同志这篇文章提出应用断裂力学原理进行喷锚支护设计,这是一种较新的尝试。但喷锚支护设计会涉及到岩石力学的许多问题,而限制岩体中裂缝的扩展只是其中的一个内容。我们希望通过多方面的探讨来推动这项技术的发展,欢迎读者积极参加研究讨论。
The technology of shotcrete and bolt support in underground engineering has many advantages. However, due to the insufficient research on its working mechanism, it is not yet a complete and scientific design method at present, so that the popularization and application of this technology is affected to some extent. Comrade Tao Zhenyu this article put forward the application of fracture mechanics spray anchor support design, which is a relatively new attempt. However, spray-anchor support design involves many problems in rock mechanics, and limiting the expansion of cracks in rock mass is only one of them. We hope that through various discussions to promote the development of this technology, readers are welcome to participate actively in the discussion.
