	<span style=\"font-size:14px;line-height:1.5;\">以蒙华铁路某隧道小间距段为工程背景，基于弹塑性有限单元法对小间距隧道段的开挖和支护全过程进行三维数值模拟，分析了小间距段隧道受力和变形特性，并结合现场实测数据进行对比。结果显示：在围岩较好条件下，小间距隧道采用全断面法开挖，可有效地控制小间距隧道的应力集中和变形，数值模拟计算结果与现场测试结果基本吻合，为小间距隧道的设计和施工提供了理论依据和指导。<br />
Taking the small-spacing tunnel of the Menghua Railway as an engineering background, based on the elasto-plastic finite element method, the three-dimensional numerical simulation of the excavation and support of the small-spacing tunnel was carried out. The stress and deformation characteristics of small-spacing tunnel were analyzed and compared with the field measurement data. The results show that the numerical simulation results are basically consistent with the field test results, which provides a theoretical basis and guidance for the design and construction of the small-spacing tunnel.</span>
