| 摘 要： | TBM施工前的步进工作顺利与否,直接关系到整座隧道的施工工期。弧形基础是保证TBM步进的关键性附属设施之一。在应用ANSYS软件对弧形基础设计验算基础上,对其施工组织、施工顺序、工艺流程、模板安装、混凝土浇注及养护等进行介绍。通过TBM步进效果信息反馈,施工方法能满足TBM步进安全通过预备洞段,取得了良好的技术和经济效益。

| Abstract: | The success of steeping work before TBM construction is directly related to the construction period of the whole tunnel.Arc foundation is one of the key auxiliary facilities for TBM steeping.On the basis of checking arc foundation design using ANSYS software,the construction organization,construction sequence,process flow,framework installation,concrete placement and curing are introduced in this paper.Through TBM stepping effect feedback,it is proven that this construction method can satisfy TBM step passing the preliminary hole safely,which has achieved god technical and economical benefit. |
