A new chorded arch bridge is put forward by Professor Zhixiang zhou of Chongqing Jiaotong University. For further exploration by the bridge design and construction scheme of the feasibility and rationality, and to verify the correctness of the theoretical analysis and probe the effective measures to deal with the closure error during in the rotating construction, a model made with by organic glass (ratio of the model to original bridge is 1/10) is has been experimented. In this test, the rotating down procedure of the construction was simulated and studied, possible closure errors were tested and corresponding measures are proposed, and the mechanical performances at key stages of construction and service were examined. Plentiful experimental data and some new knowledge about the chorded arch bridge were obtained from this test, which provided reliable technical guarantee for the actual construction.
