曲线连续刚构梁桥施工过程中变形控制分析

Analysis of Deformation Control in Construction Process of Curved Continuous Rigid Frame Bridge

预应力混凝土结构形式是连续刚构桥的主要形式,桥墩则是固结的连续性梁桥。这种桥的优点是具有很强的适用性且外形比较美观,在结构上具有较强的刚度,能跨越较长的距离,而且对于所受力的分布较合理。基于以上几种优点,这种桥已在大河及深谷中得到广泛的应用。因此,在刚构桥的施工中确保桥梁结构的美观性和平稳性的同时,还需使桥梁具备一定的承载能力和抗震能力,在进行连续性刚构桥施工时须确保技术水平。

The form of prestressed concrete in structure is the main form of continuous steel bridge, and the pier is a continuous bridge with consolidation. The advantages of this bridge are very strong applicability, and the appearance is relatively beautiful, with strong stiffness in the structure, can span a long distance, and the distribution is very reasonable. Based on these advantages, the bridge has been widely used in the river and deep valleys. Therefore, we ensure the beautiful and peaceful stability of the bridge structure in the construction of the steel structure bridge, but also to allow the bridge to have a certain bearing capacity and seismic capacity, which requires the continuous construction of steel bridge construction must have excellent construction technology.
