THE RESEARCH OF STRESS MONITORING IN CONSTRUCTION STAGE OF CONCRETE CONTINUOUS BRIDGE

摘要

This paper presents the situation of the fiber optic strain sensor first used in the stress monitoring of concrete continuous bridge construction stage. Favorable research is done that how to delete the influence of temperature and concrete shrinkage, creep from measured strain, and how to calculate the real stress of structure is proceeded in this paper. A suitable analysis method is supplied for the data-processing of measured strain data. The achievement can supply experience for the further work.
