摘　　要：通过数值仿真,分析了单心圆、尖三心圆、坦三心圆3种隧道衬砌结构型式的结构各部分的力学性状,比较了各衬砌断面型式的优缺点,经综合比较,给出了较为合理的黄土公路隧道的衬砌断面型式。研究结论可为今后合理地设计隧道衬砌结构提供可靠的依据。With the help of numerical simulation, the mechanical properties of three different forms of lining structures of highway tunnel （such as single-center circle, three-center sharp circle, three-center tabular circle） are analyzed. A rational form of lining sections for highway tunnel in loess is presented by comprehensive comparison. The results offer the reliable laboratory data for the design of reasonable lining structure of highway tunnel.
