隧道上方基坑工程施工技术研究

随着城市建设的发展,许多工程的施工受城市其他构筑物的影响也越来越多,而对构筑物保护要求也越来越高。该文以上海某工程为实例,结合有限元分析法,探索了隧道上方工程施工的方法。施工监测的结果表明该工程所采用的施工工艺较好地控制了下伏隧道的位移,达到了设计和有关规范的要求。

Study on Engineering Construction Technology of Foundation Pit at Upper of Tunnel

With the development of city construction,the construction of many projects is more and more influenced by the other structures of city,and the protective requirements of the structures are higher and higher.Taking a project of Shanghai as a case,the article discusses the method of engineering construction at the upper of tunnel by the finite element analysis method.The result of construction monitor shows that the construction technology used in this project better controls the displacement of underlying tunnel,and satisfies the requirements of design and the relative standards.
