In this paper we dissertate the common structure cross forms and excavating methods of highway double - arc tunnel home and abroad at the first part, and study common simulation methods of tunnel construction afterwards. based on the method of reversing and releasing the stress, and combined with the capacity of simulating continuous construction of ansys programme, we come up with the thought of using the method of applying virtual support force to release the stress step by step to realize the step - by - step release of initial stress during the tunnel construction simulation. with the help of design language of ansys, we develop a command to apply the virtual support force
探討了應用平面應變模型進行隧道施工過程模擬的常用方法，在「反轉應力釋放法」的基礎上，結合ansys軟體可以模擬連續施工的特點，提出利用「施加虛擬支撐力逐步釋放法」來實現隧道施工過程中地應力隨工序的逐步釋放的思路，並且利用ansys的apdl設計語言，開發出施加虛擬支撐力的命令，實現了施工過程中應力的逐步釋放，從而找到了一種模擬隧道施工過程的好方法。 -
Then we simulate the common excavating methods of double - arc tunnel respectively, analyze the stress and strain of wall rock and support structure of each method, and recommend the best excavating method to construct double - arc tunnel in wall rocks of ii. then we analyze the " three headings method " in detail, and also simulate the effect of construction factor, stress releasing coefficient and secondary lining
對實際工程中最常用的三種開挖方法分別進行了施工模擬，分析了它們各自的圍巖和支護的受力變形規律，經比較后，得出了三導洞法是類圍巖中修建連拱隧道的較好開挖方法的結論。 -
Mechanism of the milling distortion caused by initial residual stress of workpiece is analyzed. formulae of stress re - distribution and distortion by stress releasing during milling process are deduced by elasticity theory. the calculation software is developed for the formulae
