英文摘要：

Based on fiber bragg grating（FBG） sensor and construction supervision system,the construction supervision of heating engineering bridge on Hulan river was realized combined with numerical simulation technology.Firstly,according to the technique principle of FBG,the supervision system was designed combined with construction scheme;secondly,according to the construction supervision principle,the control index with two parameters was put forward combined with the analysis of construction process.Finally,according to actual construction supervision,the theory analysis and actual measuring result were compared and the numerical analysis model was modified.This system can provide supports for the construction realizing expected design goal.
