The arch bending on the top of the original main arch ring corresponds to every arch rib and the bottom beam on its landscape orientation. As a result it becomes a down arc frame similar to slab-and-beam floor system. On the arch bending and bottom beam just established, standing pillar, main beam, horizontal rib beam and bridge front-panel would be built subsequently. Both ends of the main beam would then be put off the new hat beam made of reinforced concrete. Now, it becomes an upper slab-and-beam floor system. Two decks will be joined together on the middle of the bridge, which forms the ability of spanning and loading.

在原主拱圈拱肋相应位置处增设拱伏，横向增设底梁，形成一个下层弧形的类似肋梁楼盖的结构；在已浇筑好的拱伏与底梁上，继续现浇立柱、主梁和横向肋梁、桥面板，主梁的两端搁置在桥台处新增加的钢筋混凝土台帽梁上，形成一个上层肋梁楼盖结构，并且上下两层楼盖在桥梁跨中互为渗透结合成一个牢固的整体，共同完成了跨越和承载的能力。

Based on the differences between the design value and the survey of the bridge deck elevation in constructing the pre-stressed and so on working condition, the model parameters are identified by ANN, and the beam camber of different sections are given. The results demonstrated that the ANN is efficient and the theoretical results fit well with that of forecasting the beam camber in construction.In this thesis, aim to the beam axis shape be exactitude for design, the internal force of the beam be appeased by design request, the concept of modem cybernetics is applied, At the same time, the effecting parameter has collected. The paper build the ANN model in predicting the beam camber an construction and discuss indetail the extraction of inputting nodes information when quoting the fundamental principle of ANN model and introducing research process of the improved BNN. According to them, ANN is applied in the construction control of prestressed concrete continuous bridge. It is successful for used in the No. 4 bridge of Xiangfan bridge over-crossing Hanriver brideg. To predict the construction camber of by ANN method is useful and effective.
