| Abstract: | Targeting the continuous beam-arch composite bridge in Peking-Tianjian Intercity Railway, this paper analyses theoretically the strain control of the bridge＇ s cast-in-place cantilever and steel tubular concrete arch. It has also found a valid controlling system according to the construction practice, which will insure the structure＇ s stability during its construction, and insure the bridge＇ s safety and endurance during its operation |
