摘　　要：为研究巷道在集中应力作用下围岩的变形规律,对于特定的工程条件进行相似材料模型实验。在数据采集上应用数码照相量测技术,对实验模型进行连续照相,以分析围岩位移场以及特定点位移的变化。分析结果表明,模型巷道围岩在临近洞口开挖的情况下,会产生相应于应力释放和应力集中的位移,最终位移是两者叠加的结果。To study the deformation of mine tunnel in stress concentration areas, model test of given engineering conditions is carried out. Digital photography-based deformation measurement technique is used for the parameters collection. Continuous pictures of the test model are taken for the analysis of tun- nel surrounding rock displacement and displacement of the specifically points. The results show that tunnel-surrounding rocks tend to result in displacement when the near tunnel is dug, and in the superposition of the stress relief and the stress concentrations. The results also show the advantage of digital photography-based deformation measurement technique used in the model test.
