摘　　要：对对称双连拱隧道采用连续介质模型并应用ANSYS有限元软件进行结构的最优组合设计。根据ANSYS软件计算所得结果模拟出相应的应力云图,并进行对比分析,得出取P=60°时的对称双连拱隧道模型作为最优组合设计的重要结论。This paper adopts continuous medium models for the symmetrical double continuous arch tunnel, and analyses them with ANSYS to make the optimal combination design. By comparing and analyzing and based on the relative stress cloud charts which are simulated according to the computation effect of ANSYS, the key conclusion that the model of symmetrical double continuous arch tunnel as P equals to 60 degree is the optimal combination design is acquired.
