Aiming at the problem of hard to monitor features such as temperature, strain in time in large concrete pouring construction process during the construction of urban underground substation, this paper presents applying fiber Bragg grating sensors to collect temperature and strain data in the process of concrete pouring, then demodulating them, and transmitting them to the computer terminal, finally proceeding the real-time online monitoring. Moreover, this paper establishes the 3D models of temperature field and strain field on the basis of one pouring pile, then proceeds dynamic simulation and real-time observation, which can provide certain theoretical support and technical guidance for the site construction, further improve work efficiency, safety and reliability.
