摘要
城市之光(City of Ligths)由4栋住宅和1栋办公楼组成的建筑群,均为30层以上的高层建筑,每层的大柱网或大跨度处采用后张法预应力施工技术。分析了预应力施工原理与工艺流程,以及预应力施工的准备工作,如施工材料准备、施工机具准备,详细描述了预应力施工的内容。最后,提出了预应力施工质量和安全问题的应对及预防措施。
The City of Lights project consists of four residential towers and one office tower.All the towers are high-rise buildings of more than 30 stories.The post-tension construction technology is applied to locations with large column spaces or long spans on every floor.This paper analyzes the principle and process flow of post-tension construction technology,and the preparation work before construction,such as materials preparation,construction machines preparation.Details of the contents of post-tension construction are also described.Finally,the paper put forward methods to deal with the post-tension construction quality and safety problems as well as the preventive measures.
