摘要
随着社会的发展,人们对建筑物的功能要求越来越苛刻,超大空间、超大跨度的建筑物逐年增多,而预应力技术能减少钢筋用量和构件截面尺寸从而达到节省材料、减少自重等目的,因此预应力技术运用越来越广。介绍了无锡恒隆广场工程中的预应力施工工艺,阐述了在施工过程中遇到的问题及其处理方案,并总结了施工质量、安全和进度的控制措施。
With the development of society,people are increasingly demanding functional requirements of the buildings,which have large spaces and large-span. The prestressed technology can reduce the crosssectional dimensions and steel bars dosage to achieve material savings,reduce weight and other purposes.Therefore the prestressed technology is accepted more and more widely. This paper introduces the construction process of prestress in Wuxi Hang Lung Plaza project,explains the problem encountered in the construction process and its treatment options,and then summarizes the control measures of the construction quality,safety and progress.
