考虑时空效应的围护结构支撑轴力实测结果分析研究

STUDY ON STRUTTING FORCE WITH RESPECT TO TIME-SPACE EFFECT IN EXCAVATION

通过对采用时空效应法施工的地铁车站深基坑开挖全过程支撑轴力及相应工况的跟踪记录，以及相应的监测数据资料的全面分析，探讨了应用时空效应规律而进行的基坑开挖过程中围护结构支撑轴力变化的一些规律，并且提出了考虑时空效应的围护结构设计中在支撑轴力取值方面的一些建议。

On the basis of the whole range cases of excavation and corresponding monitoring strut force for various cases being observed, this paper studies the variation of strutting force during a metro station excavation which is under conduction of timespace effect theory. Proposals are presented for braced structure design considering timespace effect during excavation.
