摘　　要：假定隧道二次衬砌处于稳定围岩压力作用下,采用"田"字形支撑结构,利用结构力学刚性连接形式,推导出了结构内力与变形计算公式,并且通过实际工程案例作了计算分析,指出利用结构力学方法推导的计算公式为隧道衬砌支撑结构计算提供了新途径。This paper assumes that the tunnel lining is in the stable surrounding rock pressure, the internal force of the structure and deformation calculation formula are derived by using the ＂Tian＂ font support structure and rigid connection type in structural mechanics principle. Through the practical engineering case made calculation and analysis, pointed out that using structural mechanic method derived the calculation formula provided a new way for the calculation of tunnel lining support structure.
