摘要
以我国某隧道工程为实际案例,合理采用三维有限元解析法对隧道工程进行研究,进一步深入探讨隧道工程应用明挖法进行施工是否会对近接桥梁桩基造成影响,是否会产生变形情况。研究结果表明,隧道工程对近接桥梁桩基进行施工时,相应位置出现了比较显著的变形,同时基坑侧墙的部分区域也发生了变形情况。针对此现象,笔者提出了与之相应的施工建议,为今后相似的隧道工程施工提供了强有力依据。
Taking some tunnel project in China as an example,this paper applies three-dimensional finite element method to study the tunnel engineering reasonably,further discusses if the open-cut dig used in the tunnel construction will affect the quality of bridge pile foundation or if it will produce deformation.The research results show that their occurs significant deformation of pile foundation around which the tunnel is constructed,and some deformation happens in part of the slide walls of foundation pit.Aiming at these problems,the author puts forward the corresponding construction advice and provides a strong basis for the similar tunnel engineering construction.
