基于位移反分析的隧道参数模拟研究

Application of the Displacement Back Analysis in the Construction of City-Highway Tunnel

目前,隧道工程信息化施工应用十分普遍,而反演分析是信息化施工的核心内容。位移量测反演分析作为目前最常用的一种,有它独特的优点。文章结合它在某城市公路隧道中的应用,介绍了其计算方法。计算结果表明,应用该方法,可以获得比较符合地质条件和工程应用的结论,据此可以回馈原设计方案并进行修正,反演的结果可以作为工程的参考资料。文章还对该方法的发展前景作了展望,提出了需要进一步解决的问题。

Tunnel engineering information construction has been widely used, and the back analysis is its core. As the common useful method, displacement back analysis is of special advantages. This article simply introduces the calculative method based on the application in the city-highway tunnel. The result shows that the conclusion in accordance with the geological condition and project application can be gained by this method, by which the primary design can be modified and the back-analysis result can be as reference for the engineering. This paper also discusses the foreground of the method and presents some problems of the further solution.
