摘要
在地下工程中,当洞室穿越断层、节理等破碎带时,应尽可能使洞轴线走向与破裂面的走向呈大角度相交(≤90°)。然而如何设计洞室轴线走向与破裂面走向大角度相交,一直缺乏具体而简易的计算方法,尤其在破裂面较多且产状明显不同时,这个问题更为突出。文章对洞室穿越一组、二组和三组节理的情况,作了探讨,提出相应的计算原则和具体公式。
In underground engineering, the cavity axis should be designed to intersect fractures with large-angle(≤ 90°)as it traverses fault and joints. There is short of specific and simple calculating method to obtain the cavity axis' orientation, especially for the rocks with many fractures. In this paper, the authors probe into this problem and bring forward relevant principles and formulae under the condition that the cavity traverses different joints.
