深基坑工程信息化施工中反馈的变形信息
|
摘要
由于设计的局限性以及参数的不确定性 (具有上下限 ) ,深基坑开挖中难免会遇到一些意外的困难。信息化施工是对设计最好的补充和完善 ,特别是反馈的变形信息能够比较直观地反映支护结构及其邻近建 (构 )筑物的稳定情况 ,因而对开挖具有指导性的作用。本文结合一具体实例说明变形信息以及正确处理变形信息的重要性。
It can not be avoided to encounter some difficulties in the excavation of deep foundation pit due to the limitation of design and inaccuracy of parameter. Information construction is the best complement and perfection design, especially, the feedback information of deformation can reflect stability of the supporting structure and neighbouring building directly, therefore , it is instructive to the excavation. In the paper, an example is given to emphasize the importance of deformation information and its correct treatment.
