| Abstract: | Combining with the construction of a large span prestressed continuous beam bridge, this paper introduces its con- tents and method of construction monitoring. The bridge main structure is simulated and the theoretical values of each con- struction stage are extracted by finite element simulation method. The main bridge structure alignment and stress of cantilever construction process are also monitored to guide the construction. |
