天津周大福金融中心深基坑变形综合控制技术

Comprehensive Control Technology for the Deformation of Deep Foundation Excavation in Tianjin CTF Financial Center Project

以天津周大福金融中心为工程背景,基坑周边环境复杂,毗邻众多重要建筑物,管线密集且部分管线变形已经达到预警值,同时地处天津软土地区的基坑存在着显著的"时空效应",基坑变形引起的负面影响不言而喻,其是整个工程顺利实施的前提,也是工程成败的关键。

In this paper,based on Tianjin CTF Financial Center project,the surrounding environment around the foundation excavation is complex,adjacent to many important buildings,pipeline-intensive and part of the pipeline deformation reaches the early warning value,while located in Tianjin soft soil area there is a significant ＂space-time effect＂,the negative impact caused by the deformation of the deep foundation excavation is self-evident,which is the prerequisite for the smooth implementation of the whole project and also the key to the success or failure of the project.
