| 中文摘要: |
| 无应力状态法是一种用于施工控制的先进理论方法，该方法大大方便了施工控制过程。在中国市场上具有无应力状态法专业分析模块的软件很少，即便是广泛使用的MIDAS Civil软件也无此模块。本文就此提出了利用一般有限元软件进行无应力状态法分析的方法、流程和注意事项，并通过MIDAS Civil建立一钢箱梁斜拉桥有限元模型进行验证。结果表明，该方法完全能够以常规有限元软件为平台来实现无应力状态法。 |

| Unstressed state method is a kind of advanced theoretical construction control method, which could highly simplify the construction monitoring work. But in the market, there are very rare software that include this specialized module, even the most popular software 《MIDAS Civil. To solve this problem, a very effective analysis process and the points for attention are presented in this paper. The effectiveness of this process was tested by a finite element modal of cable stayed bridge with steel box girder, and the result show that this process could be used in construction analysis based on unstressed state method. |
