摘要
在地下工程尤其是高地应力分布区围岩稳定性分析中,必须考虑岩石的流变特性。为了更好的控制巷道围岩变形,本文从蠕变的角度,对高地应力下巷道围岩进行分析研究,利用FLAC3D数值模拟软件进行模拟分析,提出不同的支护方案,并提出对工程实践有指导意义的支护建议。
In the analysis of the stability of surrounding rock which is in underground engineering especially in high geostress, the rheological properties of rocks must be considered. In order to control the deformation of surrounding rocks more effectively, the surrounding rocks under high geostress were analyzed simulalion software--FLAC3D, some protection plans were proposed, and in the sides of the creep using the numerical some suggestions guiding to support the miningengineering were proposed.
