世博轴作为世博会园区最大的一个单体建筑,在整个改建过程中,须对原结构进行大范围拆除、新建。由于原结构有大量大跨度预应力结构,因此在改造过程中对于这些预应力结构的拆除、新建及监测成为了结构实施的关键。通过世博轴改造工程实例,介绍了对不同类型的预应力结构处置的一系列措施,不仅保证了新结构的整体质量,还为后续类似项目的实施提供了经验和借鉴。
As one of the largest single buildings in the World Expo Park, the Expo Axis must be demolished and newly built in the entire reconstruction process. Since the original structure has a large number of large-span prestressed structures, the demolition, new construction and monitoring of these prestressed structures are the keys to the structural implementation during the reconstruction process. A series of measures to deal with different types of prestressed structures are introduced through the World Expo Axis Reconstruction Project, which not only ensures the overall quality of the new structure, but also provides experiences for the follow-up of similar projects.
