EARLYAGE TEMPERATURE AND CREEP MONITORING FOR SUBWAY STATION STRUCTURE
Through the structure health monitoring on Guomao Station, a series experiments of temperature and creep for the earlyage mass concrete of the station structure were conducted during construction, by using Fiber Bragg Grating (FBG) sensors and vibrating wire (VW) sensors. Based on the theory of creep and heat of hydration of earlyage concrete, the temperature and creep of soleplates and septi-plate are calculated by Finite Element (FE) method, and influences of creep on the strain of structure members are analyzed. Experiment data measured by the two type of sensors agree very well, and the calculated results taking into account the earlyage creep are better in agreement with the measured data.
