摘要
地下硐室顶板被高倾角平行节理切割后 ,在沿顶板轴向方向上 ,容易形成节理梁结构。这种结构是以压力拱的形式来维持平衡的。当硐室的跨度与长度尺寸不满足平面应变条件时 ,还必须考虑顶板的几何效应及顶板内裂隙发展所带来的影响。本文详细研究了节理岩梁拱推力 ,对国内外的一些研究成果进行了改进 。
Since hundred years,the issue about stability of joint fissured roof of underground chamber is always studied by many engineers.Herein the results of the study from home and abroad,the ideas for improvement of some of these results are introduced.The focus is a detailed analysis of factors influencing the stability of square of rectangular roof of underground chamber.
