摘要
预应力技术在结构施工中应用广泛,目前较常见的有无粘结预应力技术、有粘结预应力技术及缓粘结预应力技术.缓粘结预应力施工技术具有施工方便、造价低、结构延性好、抗震性能优等特点.结合本项目对大跨缓粘结预应力技术进行总结,阐述大跨度缓粘结预应力施工技术的要点.
Abstract
Prestressed technology is widely used in structural construction.Currently,there are more common prestressed technology with or without bond,bonded prestressed technology and slow bonded prestressed technology.The construction technology of slow bonding prestressing has the characteristics of convenient construction technology,low construction cost,good ductility of structure and excellent seismic performance.Based on the summary of the long span slow bond prestressing technology of this project,the key points of long span slow bond prestressing construction technology are expounded.
