摘　　要：地道桥在正常运营和顶进施工过程中的空间受力分析是设计地道桥的重要过程,从板壳元的有限元模型四节点平板薄壳矩形应力单元和弯曲单元出发,分析编制了地道桥分析主程序进行地道桥空间受力分析,通过算例与ANSYS6.1计算相比较,验证了程序的正确性,并由此计算了一四孔地道桥。The space stress analysis is very important in the design of the tunnel bridge in the normal operation and the construction process.The FEM（finite element method） model of four node plate-shell rectangular stress element and bending element is anglicized.Using this element,a program is worked out.The solution is perfect by an example in this program compared with the calculation by ANSYS6.1.At last,a four-hole tunnel bridge is calculated by the program.
